+- * The solution we use is to do the rounding AFTER we convert the

++ * (i.e. in units of 1/2^(large scale) jiffies) but that's also

++ * combined with a division-rounding-upward (i.e. adding 2^(scale) - 1
++ * units to the intermediate before shifting) leads to accidental

++LZO stream format as understood by Linux's LZO decompressor
++===========================================================
++
++Introduction
++
++ This is not a specification. No specification seems to be publicly available
++ for the LZO stream format. This document describes what input format the LZO
++ decompressor as implemented in the Linux kernel understands. The file subject
++ of this analysis is lib/lzo/lzo1x_decompress_safe.c. No analysis was made on
++ the compressor nor on any other implementations though it seems likely that
++ the format matches the standard one. The purpose of this document is to
++ better understand what the code does in order to propose more efficient fixes
++ for future bug reports.
++
++Description
++
++ The stream is composed of a series of instructions, operands, and data. The
++ instructions consist in a few bits representing an opcode, and bits forming
++ the operands for the instruction, whose size and position depend on the
++ opcode and on the number of literals copied by previous instruction. The
++ operands are used to indicate :
++
++ - a distance when copying data from the dictionary (past output buffer)
++ - a length (number of bytes to copy from dictionary)
++ - the number of literals to copy, which is retained in variable "state"
++ as a piece of information for next instructions.
++
++ Optionally depending on the opcode and operands, extra data may follow. These
++ extra data can be a complement for the operand (eg: a length or a distance
++ encoded on larger values), or a literal to be copied to the output buffer.
++
++ The first byte of the block follows a different encoding from other bytes, it
++ seems to be optimized for literal use only, since there is no dictionary yet
++ prior to that byte.
++
++ Lengths are always encoded on a variable size starting with a small number
++ of bits in the operand. If the number of bits isn't enough to represent the
++ length, up to 255 may be added in increments by consuming more bytes with a
++ rate of at most 255 per extra byte (thus the compression ratio cannot exceed
++ around 255:1). The variable length encoding using #bits is always the same :
++
++ length = byte & ((1 << #bits) - 1)
++ if (!length) {
++ length = ((1 << #bits) - 1)
++ length += 255*(number of zero bytes)
++ length += first-non-zero-byte
++ }
++ length += constant (generally 2 or 3)
++
++ For references to the dictionary, distances are relative to the output
++ pointer. Distances are encoded using very few bits belonging to certain
++ ranges, resulting in multiple copy instructions using different encodings.
++ Certain encodings involve one extra byte, others involve two extra bytes
++ forming a little-endian 16-bit quantity (marked LE16 below).
++
++ After any instruction except the large literal copy, 0, 1, 2 or 3 literals
++ are copied before starting the next instruction. The number of literals that
++ were copied may change the meaning and behaviour of the next instruction. In
++ practice, only one instruction needs to know whether 0, less than 4, or more
++ literals were copied. This is the information stored in the <state> variable
++ in this implementation. This number of immediate literals to be copied is
++ generally encoded in the last two bits of the instruction but may also be
++ taken from the last two bits of an extra operand (eg: distance).
++
++ End of stream is declared when a block copy of distance 0 is seen. Only one
++ instruction may encode this distance (0001HLLL), it takes one LE16 operand
++ for the distance, thus requiring 3 bytes.
++
++ IMPORTANT NOTE : in the code some length checks are missing because certain
++ instructions are called under the assumption that a certain number of bytes
++ follow because it has already been garanteed before parsing the instructions.
++ They just have to "refill" this credit if they consume extra bytes. This is
++ an implementation design choice independant on the algorithm or encoding.
++
++Byte sequences
++
++ First byte encoding :
++
++ 0..17 : follow regular instruction encoding, see below. It is worth
++ noting that codes 16 and 17 will represent a block copy from
++ the dictionary which is empty, and that they will always be
++ invalid at this place.
++
++ 18..21 : copy 0..3 literals
++ state = (byte - 17) = 0..3 [ copy <state> literals ]
++ skip byte
++
++ 22..255 : copy literal string
++ length = (byte - 17) = 4..238
++ state = 4 [ don't copy extra literals ]
++ skip byte
++
++ Instruction encoding :
++
++ 0 0 0 0 X X X X (0..15)
++ Depends on the number of literals copied by the last instruction.
++ If last instruction did not copy any literal (state == 0), this
++ encoding will be a copy of 4 or more literal, and must be interpreted
++ like this :
++
++ 0 0 0 0 L L L L (0..15) : copy long literal string
++ length = 3 + (L ?: 15 + (zero_bytes * 255) + non_zero_byte)
++ state = 4 (no extra literals are copied)
++
++ If last instruction used to copy between 1 to 3 literals (encoded in
++ the instruction's opcode or distance), the instruction is a copy of a
++ 2-byte block from the dictionary within a 1kB distance. It is worth
++ noting that this instruction provides little savings since it uses 2
++ bytes to encode a copy of 2 other bytes but it encodes the number of
++ following literals for free. It must be interpreted like this :
++
++ 0 0 0 0 D D S S (0..15) : copy 2 bytes from <= 1kB distance
++ length = 2
++ state = S (copy S literals after this block)
++ Always followed by exactly one byte : H H H H H H H H
++ distance = (H << 2) + D + 1
++
++ If last instruction used to copy 4 or more literals (as detected by
++ state == 4), the instruction becomes a copy of a 3-byte block from the
++ dictionary from a 2..3kB distance, and must be interpreted like this :
++
++ 0 0 0 0 D D S S (0..15) : copy 3 bytes from 2..3 kB distance
++ length = 3
++ state = S (copy S literals after this block)
++ Always followed by exactly one byte : H H H H H H H H
++ distance = (H << 2) + D + 2049
++
++ 0 0 0 1 H L L L (16..31)
++ Copy of a block within 16..48kB distance (preferably less than 10B)
++ length = 2 + (L ?: 7 + (zero_bytes * 255) + non_zero_byte)
++ Always followed by exactly one LE16 : D D D D D D D D : D D D D D D S S
++ distance = 16384 + (H << 14) + D
++ state = S (copy S literals after this block)
++ End of stream is reached if distance == 16384
++
++ 0 0 1 L L L L L (32..63)
++ Copy of small block within 16kB distance (preferably less than 34B)
++ length = 2 + (L ?: 31 + (zero_bytes * 255) + non_zero_byte)
++ Always followed by exactly one LE16 : D D D D D D D D : D D D D D D S S
++ distance = D + 1
++ state = S (copy S literals after this block)
++
++ 0 1 L D D D S S (64..127)
++ Copy 3-4 bytes from block within 2kB distance
++ state = S (copy S literals after this block)
++ length = 3 + L
++ Always followed by exactly one byte : H H H H H H H H
++ distance = (H << 3) + D + 1
++
++ 1 L L D D D S S (128..255)
++ Copy 5-8 bytes from block within 2kB distance
++ state = S (copy S literals after this block)
++ length = 5 + L
++ Always followed by exactly one byte : H H H H H H H H
++ distance = (H << 3) + D + 1

++ * If many queues happen to become active shortly after each other, then,
++ * to help the processes associated to these queues get their job done as
++ * soon as possible, it is usually better to not grant either weight-raising
++ * or device idling to these queues. In this comment we describe, firstly,
++ * the reasons why this fact holds, and, secondly, the next function, which
++ * implements the main steps needed to properly mark these queues so that
++ * they can then be treated in a different way.
++ *
++ * As for the terminology, we say that a queue becomes active, i.e.,
++ * switches from idle to backlogged, either when it is created (as a
++ * consequence of the arrival of an I/O request), or, if already existing,
++ * when a new request for the queue arrives while the queue is idle.
++ * Bursts of activations, i.e., activations of different queues occurring
++ * shortly after each other, are typically caused by services or applications
++ * that spawn or reactivate many parallel threads/processes. Examples are
++ * systemd during boot or git grep.
++ *
++ * These services or applications benefit mostly from a high throughput:
++ * the quicker the requests of the activated queues are cumulatively served,
++ * the sooner the target job of these queues gets completed. As a consequence,
++ * weight-raising any of these queues, which also implies idling the device
++ * for it, is almost always counterproductive: in most cases it just lowers
++ * throughput.
++ *
++ * On the other hand, a burst of activations may be also caused by the start
++ * of an application that does not consist in a lot of parallel I/O-bound
++ * threads. In fact, with a complex application, the burst may be just a
++ * consequence of the fact that several processes need to be executed to
++ * start-up the application. To start an application as quickly as possible,
++ * the best thing to do is to privilege the I/O related to the application
++ * with respect to all other I/O. Therefore, the best strategy to start as
++ * quickly as possible an application that causes a burst of activations is
++ * to weight-raise all the queues activated during the burst. This is the
++ * exact opposite of the best strategy for the other type of bursts.
++ *
++ * In the end, to take the best action for each of the two cases, the two
++ * types of bursts need to be distinguished. Fortunately, this seems
++ * relatively easy to do, by looking at the sizes of the bursts. In
++ * particular, we found a threshold such that bursts with a larger size
++ * than that threshold are apparently caused only by services or commands
++ * such as systemd or git grep. For brevity, hereafter we call just 'large'
++ * these bursts. BFQ *does not* weight-raise queues whose activations occur
++ * in a large burst. In addition, for each of these queues BFQ performs or
++ * does not perform idling depending on which choice boosts the throughput
++ * most. The exact choice depends on the device and request pattern at
++ * hand.
++ *
++ * Turning back to the next function, it implements all the steps needed
++ * to detect the occurrence of a large burst and to properly mark all the
++ * queues belonging to it (so that they can then be treated in a different
++ * way). This goal is achieved by maintaining a special "burst list" that
++ * holds, temporarily, the queues that belong to the burst in progress. The
++ * list is then used to mark these queues as belonging to a large burst if
++ * the burst does become large. The main steps are the following.
++ *
++ * . when the very first queue is activated, the queue is inserted into the
++ * list (as it could be the first queue in a possible burst)
++ *
++ * . if the current burst has not yet become large, and a queue Q that does
++ * not yet belong to the burst is activated shortly after the last time
++ * at which a new queue entered the burst list, then the function appends
++ * Q to the burst list
++ *
++ * . if, as a consequence of the previous step, the burst size reaches
++ * the large-burst threshold, then
++ *
++ * . all the queues in the burst list are marked as belonging to a
++ * large burst
++ *
++ * . the burst list is deleted; in fact, the burst list already served
++ * its purpose (keeping temporarily track of the queues in a burst,
++ * so as to be able to mark them as belonging to a large burst in the
++ * previous sub-step), and now is not needed any more
++ *
++ * . the device enters a large-burst mode
++ *
++ * . if a queue Q that does not belong to the burst is activated while
++ * the device is in large-burst mode and shortly after the last time
++ * at which a queue either entered the burst list or was marked as
++ * belonging to the current large burst, then Q is immediately marked
++ * as belonging to a large burst.
++ *
++ * . if a queue Q that does not belong to the burst is activated a while
++ * later, i.e., not shortly after, than the last time at which a queue
++ * either entered the burst list or was marked as belonging to the
++ * current large burst, then the current burst is deemed as finished and:
++ *
++ * . the large-burst mode is reset if set
++ *
++ * . the burst list is emptied
++ *
++ * . Q is inserted in the burst list, as Q may be the first queue
++ * in a possible new burst (then the burst list contains just Q
++ * after this step).

++ * that, if the next request of the application does not arrive before
++ * soft_rt_next_start, then the above requirement on the bandwidth is met.
++ *
++ * The second requirement is that the request pattern of the application is
++ * isochronous, i.e., that, after issuing a request or a batch of requests,
++ * the application stops issuing new requests until all its pending requests
++ * have been completed. After that, the application may issue a new batch,
++ * and so on.
++ * For this reason the next function is invoked to compute
++ * soft_rt_next_start only for applications that meet this requirement,
++ * whereas soft_rt_next_start is set to infinity for applications that do
++ * not.
++ *
++ * Unfortunately, even a greedy application may happen to behave in an
++ * isochronous way if the CPU load is high. In fact, the application may
++ * stop issuing requests while the CPUs are busy serving other processes,
++ * then restart, then stop again for a while, and so on. In addition, if
++ * the disk achieves a low enough throughput with the request pattern
++ * issued by the application (e.g., because the request pattern is random
++ * and/or the device is slow), then the application may meet the above
++ * bandwidth requirement too. To prevent such a greedy application to be
++ * deemed as soft real-time, a further rule is used in the computation of
++ * soft_rt_next_start: soft_rt_next_start must be higher than the current
++ * time plus the maximum time for which the arrival of a request is waited
++ * for when a sync queue becomes idle, namely bfqd->bfq_slice_idle.
++ * This filters out greedy applications, as the latter issue instead their
++ * next request as soon as possible after the last one has been completed
++ * (in contrast, when a batch of requests is completed, a soft real-time
++ * application spends some time processing data).
++ *
++ * Unfortunately, the last filter may easily generate false positives if

++ * or both the following cases occur:
++ * 1) HZ is so low that the duration of a jiffy is comparable to or higher
++ * than bfqd->bfq_slice_idle. This happens, e.g., on slow devices with
++ * HZ=100.
++ * 2) jiffies, instead of increasing at a constant rate, may stop increasing
++ * for a while, then suddenly 'jump' by several units to recover the lost
++ * increments. This seems to happen, e.g., inside virtual machines.
++ * To address this issue, we do not use as a reference time interval just
++ * bfqd->bfq_slice_idle, but bfqd->bfq_slice_idle plus a few jiffies. In

-+ * If the active queue is empty, but it is sync and either of the following

-+ * expired, and 2) the disk must be idled to wait for the possible arrival

-+ * - the device is rotational and not performing NCQ, and the queue has its

-+ * is likely to boost the disk throughput);
-+ * - the queue is weight-raised (waiting for the request is necessary for
-+ * providing the queue with fairness and latency guarantees).
++ * Device idling is allowed only for the queues for which this function
++ * returns true. For this reason, the return value of this function plays a
++ * critical role for both throughput boosting and service guarantees. The
++ * return value is computed through a logical expression. In this rather
++ * long comment, we try to briefly describe all the details and motivations
++ * behind the components of this logical expression.
++ *
++ * First, the expression is false if bfqq is not sync, or if: bfqq happened
++ * to become active during a large burst of queue activations, and the
++ * pattern of requests bfqq contains boosts the throughput if bfqq is
++ * expired. In fact, queues that became active during a large burst benefit
++ * only from throughput, as discussed in the comments to bfq_handle_burst.
++ * In this respect, expiring bfqq certainly boosts the throughput on NCQ-
++ * capable flash-based devices, whereas, on rotational devices, it boosts
++ * the throughput only if bfqq contains random requests.
++ *
++ * On the opposite end, if (a) bfqq is sync, (b) the above burst-related
++ * condition does not hold, and (c) bfqq is being weight-raised, then the
++ * expression always evaluates to true, as device idling is instrumental
++ * for preserving low-latency guarantees (see [1]). If, instead, conditions
++ * (a) and (b) do hold, but (c) does not, then the expression evaluates to
++ * true only if: (1) bfqq is I/O-bound and has a non-null idle window, and
++ * (2) at least one of the following two conditions holds.
++ * The first condition is that the device is not performing NCQ, because
++ * idling the device most certainly boosts the throughput if this condition
++ * holds and bfqq is I/O-bound and has been granted a non-null idle window.
++ * The second compound condition is made of the logical AND of two components.
++ *
++ * The first component is true only if there is no weight-raised busy
++ * queue. This guarantees that the device is not idled for a sync non-
++ * weight-raised queue when there are busy weight-raised queues. The former
++ * is then expired immediately if empty. Combined with the timestamping
++ * rules of BFQ (see [1] for details), this causes sync non-weight-raised
++ * queues to get a lower number of requests served, and hence to ask for a
++ * lower number of requests from the request pool, before the busy weight-
++ * raised queues get served again.
++ *
++ * This is beneficial for the processes associated with weight-raised
++ * queues, when the request pool is saturated (e.g., in the presence of
++ * write hogs). In fact, if the processes associated with the other queues
++ * ask for requests at a lower rate, then weight-raised processes have a
++ * higher probability to get a request from the pool immediately (or at
++ * least soon) when they need one. Hence they have a higher probability to
++ * actually get a fraction of the disk throughput proportional to their
++ * high weight. This is especially true with NCQ-capable drives, which
++ * enqueue several requests in advance and further reorder internally-
++ * queued requests.
++ *
++ * In the end, mistreating non-weight-raised queues when there are busy
++ * weight-raised queues seems to mitigate starvation problems in the
++ * presence of heavy write workloads and NCQ, and hence to guarantee a
++ * higher application and system responsiveness in these hostile scenarios.
++ *
++ * If the first component of the compound condition is instead true, i.e.,
++ * there is no weight-raised busy queue, then the second component of the
++ * compound condition takes into account service-guarantee and throughput
++ * issues related to NCQ (recall that the compound condition is evaluated
++ * only if the device is detected as supporting NCQ).
++ *
++ * As for service guarantees, allowing the drive to enqueue more than one
++ * request at a time, and hence delegating de facto final scheduling
++ * decisions to the drive's internal scheduler, causes loss of control on
++ * the actual request service order. In this respect, when the drive is
++ * allowed to enqueue more than one request at a time, the service
++ * distribution enforced by the drive's internal scheduler is likely to
++ * coincide with the desired device-throughput distribution only in the
++ * following, perfectly symmetric, scenario:
++ * 1) all active queues have the same weight,
++ * 2) all active groups at the same level in the groups tree have the same
++ * weight,
++ * 3) all active groups at the same level in the groups tree have the same
++ * number of children.
++ *
++ * Even in such a scenario, sequential I/O may still receive a preferential
++ * treatment, but this is not likely to be a big issue with flash-based
++ * devices, because of their non-dramatic loss of throughput with random
++ * I/O. Things do differ with HDDs, for which additional care is taken, as
++ * explained after completing the discussion for flash-based devices.
++ *
++ * Unfortunately, keeping the necessary state for evaluating exactly the
++ * above symmetry conditions would be quite complex and time-consuming.
++ * Therefore BFQ evaluates instead the following stronger sub-conditions,
++ * for which it is much easier to maintain the needed state:
++ * 1) all active queues have the same weight,
++ * 2) all active groups have the same weight,
++ * 3) all active groups have at most one active child each.
++ * In particular, the last two conditions are always true if hierarchical
++ * support and the cgroups interface are not enabled, hence no state needs
++ * to be maintained in this case.
++ *
++ * According to the above considerations, the second component of the
++ * compound condition evaluates to true if any of the above symmetry
++ * sub-condition does not hold, or the device is not flash-based. Therefore,
++ * if also the first component is true, then idling is allowed for a sync
++ * queue. These are the only sub-conditions considered if the device is
++ * flash-based, as, for such a device, it is sensible to force idling only
++ * for service-guarantee issues. In fact, as for throughput, idling
++ * NCQ-capable flash-based devices would not boost the throughput even
++ * with sequential I/O; rather it would lower the throughput in proportion
++ * to how fast the device is. In the end, (only) if all the three
++ * sub-conditions hold and the device is flash-based, the compound
++ * condition evaluates to false and therefore no idling is performed.
++ *
++ * As already said, things change with a rotational device, where idling
++ * boosts the throughput with sequential I/O (even with NCQ). Hence, for
++ * such a device the second component of the compound condition evaluates
++ * to true also if the following additional sub-condition does not hold:
++ * the queue is constantly seeky. Unfortunately, this different behavior
++ * with respect to flash-based devices causes an additional asymmetry: if
++ * some sync queues enjoy idling and some other sync queues do not, then
++ * the latter get a low share of the device throughput, simply because the
++ * former get many requests served after being set as in service, whereas
++ * the latter do not. As a consequence, to guarantee the desired throughput
++ * distribution, on HDDs the compound expression evaluates to true (and
++ * hence device idling is performed) also if the following last symmetry
++ * condition does not hold: no other queue is benefiting from idling. Also
++ * this last condition is actually replaced with a simpler-to-maintain and
++ * stronger condition: there is no busy queue which is not constantly seeky
++ * (and hence may also benefit from idling).
++ *
++ * To sum up, when all the required symmetry and throughput-boosting
++ * sub-conditions hold, the second component of the compound condition
++ * evaluates to false, and hence no idling is performed. This helps to
++ * keep the drives' internal queues full on NCQ-capable devices, and hence
++ * to boost the throughput, without causing 'almost' any loss of service
++ * guarantees. The 'almost' follows from the fact that, if the internal
++ * queue of one such device is filled while all the sub-conditions hold,
++ * but at some point in time some sub-condition stops to hold, then it may
++ * become impossible to let requests be served in the new desired order
++ * until all the requests already queued in the device have been served.

++/* Support code for asymmetrically connected dgram sockets
++ *
++ * If a datagram socket is connected to a socket not itself connected
++ * to the first socket (eg, /dev/log), clients may only enqueue more
++ * messages if the present receive queue of the server socket is not
++ * "too large". This means there's a second writeability condition
++ * poll and sendmsg need to test. The dgram recv code will do a wake
++ * up on the peer_wait wait queue of a socket upon reception of a
++ * datagram which needs to be propagated to sleeping would-be writers
++ * since these might not have sent anything so far. This can't be
++ * accomplished via poll_wait because the lifetime of the server
++ * socket might be less than that of its clients if these break their
++ * association with it or if the server socket is closed while clients
++ * are still connected to it and there's no way to inform "a polling
++ * implementation" that it should let go of a certain wait queue
++ *
++ * In order to propagate a wake up, a wait_queue_t of the client
++ * socket is enqueued on the peer_wait queue of the server socket
++ * whose wake function does a wake_up on the ordinary client socket
++ * wait queue. This connection is established whenever a write (or
++ * poll for write) hit the flow control condition and broken when the
++ * association to the server socket is dissolved or after a wake up
++ * was relayed.

+ JFFS2 LOCKING DOCUMENTATION
+ ---------------------------

+-At least theoretically, JFFS2 does not require the Big Kernel Lock
+-(BKL), which was always helpfully obtained for it by Linux 2.4 VFS
+-code. It has its own locking, as described below.
+-
+ This document attempts to describe the existing locking rules for
+ JFFS2. It is not expected to remain perfectly up to date, but ought to
+ be fairly close.

++ * @target_offset: the arp/ip/ip6_t->target_offset
++ * @next_offset: the arp/ip/ip6_t->next_offset
++ *
++ * validates that target_offset and next_offset are sane and that all
++ * match sizes (if any) align with the target offset.
++ *
++ * This function does not validate the targets or matches themselves, it
++ * only tests that all the offsets and sizes are correct, that all
++ * match structures are aligned, and that the last structure ends where
++ * the target structure begins.
++ *
++ * Also see xt_compat_check_entry_offsets for CONFIG_COMPAT version.
++ *
++ * The arp/ip/ip6t_entry structure @base must have passed following tests:
++ * - it must point to a valid memory location
++ * - base to base + next_offset must be accessible, i.e. not exceed allocated
++ * length.
++ *
++ * A well-formed entry looks like this:
++ *
++ * ip(6)t_entry match [mtdata] match [mtdata] target [tgdata] ip(6)t_entry
++ * e->elems[]-----' | |
++ * matchsize | |
++ * matchsize | |
++ * | |
++ * target_offset---------------------------------' |
++ * next_offset---------------------------------------------------'
++ *
++ * elems[]: flexible array member at end of ip(6)/arpt_entry struct.
++ * This is where matches (if any) and the target reside.
++ * target_offset: beginning of target.
++ * next_offset: start of the next rule; also: size of this rule.
++ * Since targets have a minimum size, target_offset + minlen <= next_offset.
++ *
++ * Every match stores its size, sum of sizes must not exceed target_offset.

++ * The 32-bit x86 assembler in binutils 2.26 will generate R_386_GOT32X
++ * relocation to get the symbol address in PIC. When the compressed x86
++ * kernel isn't built as PIC, the linker optimizes R_386_GOT32X
++ * relocations to their fixed symbol addresses. However, when the
++ * compressed x86 kernel is loaded at a different address, it leads
++ * to the following load failure:
++ *
++ * Failed to allocate space for phdrs
++ *
++ * during the decompression stage.
++ *
++ * If the compressed x86 kernel is relocatable at run-time, it should be
++ * compiled with -fPIE, instead of -fPIC, if possible and should be built as
++ * Position Independent Executable (PIE) so that linker won't optimize
++ * R_386_GOT32X relocation to its fixed symbol address. Older
++ * linkers generate R_386_32 relocations against locally defined symbols,
++ * _bss, _ebss, _got and _egot, in PIE. It isn't wrong, just less
++ * optimal than R_386_RELATIVE. But the x86 kernel fails to properly handle
++ * R_386_32 relocations when relocating the kernel. To generate
++ * R_386_RELATIVE relocations, we mark _bss, _ebss, _got and _egot as
++ * hidden:

+Date: Thu, 16 Feb 2017 17:22:46 +0100
+Subject: dccp: fix freeing skb too early for IPV6_RECVPKTINFO
+
+In the current DCCP implementation an skb for a DCCP_PKT_REQUEST packet
+is forcibly freed via __kfree_skb in dccp_rcv_state_process if
+dccp_v6_conn_request successfully returns.
+
+However, if IPV6_RECVPKTINFO is set on a socket, the address of the skb
+is saved to ireq->pktopts and the ref count for skb is incremented in
+dccp_v6_conn_request, so skb is still in use. Nevertheless, it gets freed
+in dccp_rcv_state_process.
+
+Fix by calling consume_skb instead of doing goto discard and therefore
+calling __kfree_skb.
+
+Similar fixes for TCP:
+
+fb7e2399ec17f1004c0e0ccfd17439f8759ede01 [TCP]: skb is unexpectedly freed.
+0aea76d35c9651d55bbaf746e7914e5f9ae5a25d tcp: SYN packets are now
+simply consumed
