++ * Removing an inode from the namespace involves removing the directory entry

++ * result in locking an AGF (directory blocks were freed) and removing a link
++ * count can result in placing the inode on an unlinked list which results in
++ * locking an AGI.
++ *
++ * The big problem here is that we have an ordering constraint on AGF and AGI
++ * locking - inode allocation locks the AGI, then can allocate a new extent for
++ * new inodes, locking the AGF after the AGI. Similarly, freeing the inode
++ * removes the inode from the unlinked list, requiring that we lock the AGI
++ * first, and then freeing the inode can result in an inode chunk being freed
++ * and hence freeing disk space requiring that we lock an AGF.
++ *
++ * Hence the ordering that is imposed by other parts of the code is AGI before
++ * AGF. This means we cannot remove the directory entry before we drop the inode
++ * reference count and put it on the unlinked list as this results in a lock
++ * order of AGF then AGI, and this can deadlock against inode allocation and
++ * freeing. Therefore we must drop the link counts before we remove the
++ * directory entry.
++ *
++ * This is still safe from a transactional point of view - it is not until we
++ * get to xfs_bmap_finish() that we have the possibility of multiple
++ * transactions in this operation. Hence as long as we remove the directory
++ * entry and drop the link count in the first transaction of the remove
++ * operation, there are no transactional constraints on the ordering here.

++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

++Unfortunately, a single memory access might access kvm_memslots(kvm) multiple
++times, the last one happening when the generation number is retrieved and
++stored into the MMIO spte. Thus, the MMIO spte might be created based on
++out-of-date information, but with an up-to-date generation number.
++
++To avoid this, the generation number is incremented again after synchronize_srcu
++returns; thus, the low bit of kvm_memslots(kvm)->generation is only 1 during a
++memslot update, while some SRCU readers might be using the old copy. We do not
++want to use an MMIO sptes created with an odd generation number, and we can do
++this without losing a bit in the MMIO spte. The low bit of the generation
++is not stored in MMIO spte, and presumed zero when it is extracted out of the
++spte. If KVM is unlucky and creates an MMIO spte while the low bit is 1,
++the next access to the spte will always be a cache miss.

+- * We translate the PMD by hand, one bit at a time,

+- *
+- * So we construct the PTE in REG2 as follows:
+- *
+- * 1) Extract the PMD PFN from REG1 and place it into REG2.
+- *
+- * 2) Translate PMD protection bits in REG1 into REG2, one bit
+- * at a time using andcc tests on REG1 and OR's into REG2.
+- *
+- * Only two bits to be concerned with here, EXEC and WRITE.
+- * Now REG1 is freed up and we can use it as a temporary.
+- *
+- * 3) Construct the VALID, CACHE, and page size PTE bits in
+- * REG1, OR with REG2 to form final PTE.
++ * We have to propagate the 4MB bit of the virtual address

++ * 1) Several OSs, Solaris and Linux included, use them even when only

++ * hypervisor has a workaround that provides the VIRQ interfaces even
++ * when only verion 1.0 of the API is in use.
++ *
++ * 2) Second, and more importantly, with major version 2.0 these VIRQ
++ * interfaces only were actually hooked up for LDC interrupts, even
++ * though the Hypervisor specification clearly stated:
++ *
++ * The new interrupt API functions will be available to a guest
++ * when it negotiates version 2.0 in the interrupt API group 0x2. When
++ * a guest negotiates version 2.0, all interrupt sources will only
++ * support using the cookie interface, and any attempt to use the
++ * version 1.0 interrupt APIs numbered 0xa0 to 0xa6 will result in the
++ * ENOTSUPPORTED error being returned.
++ *
++ * with an emphasis on "all interrupt sources".
++ *
++ * To correct this, major version 3.0 was created which does actually

++Typically the default value of mem_type=0 should be used as that sets the pstore

++ * the interrupt handler would be called immediately and the i2c command
++ * would be reported as completed.
++ * Also when a write transaction is managed by the DMA controller,

+- * read_barrier_depends - Flush all pending reads that subsequents reads
+- * depend on.
+- *
+- * No data-dependent reads from memory-like regions are ever reordered
+- * over this barrier. All reads preceding this primitive are guaranteed
+- * to access memory (but not necessarily other CPUs' caches) before any
+- * reads following this primitive that depend on the data return by
+- * any of the preceding reads. This primitive is much lighter weight than
+- * rmb() on most CPUs, and is never heavier weight than is
+- * rmb().
+- *
+- * These ordering constraints are respected by both the local CPU
+- * and the compiler.
+- *
+- * Ordering is not guaranteed by anything other than these primitives,
+- * not even by data dependencies. See the documentation for
+- * memory_barrier() for examples and URLs to more information.
+- *
+- * For example, the following code would force ordering (the initial
+- * value of "a" is zero, "b" is one, and "p" is "&a"):
+- *
+- * <programlisting>
+- * CPU 0 CPU 1
+- *
+- * b = 2;
+- * memory_barrier();
+- * p = &b; q = p;
+- * read_barrier_depends();
+- * d = *q;
+- * </programlisting>
+- *
+- *
+- * because the read of "*q" depends on the read of "p" and these
+- * two reads are separated by a read_barrier_depends(). However,
+- * the following code, with the same initial values for "a" and "b":
+- *
+- * <programlisting>
+- * CPU 0 CPU 1
+- *
+- * a = 2;
+- * memory_barrier();
+- * b = 3; y = b;
+- * read_barrier_depends();
+- * x = a;
+- * </programlisting>
+- *
+- * does not enforce ordering, since there is no data dependency between
+- * the read of "a" and the read of "b". Therefore, on some CPUs, such
+- * as Alpha, "y" could be set to 3 and "x" to 0. Use rmb()
+- * in cases like this where there are no data dependencies.

+-** This is simply the barrier() macro from linux/kernel.h but when serial.c
+-** uses tqueue.h uses smp_mb() defined using barrier(), linux/kernel.h
+-** hasn't yet been included yet so it fails, thus repeating the macro here.
+-**
+-** PA-RISC architecture allows for weakly ordered memory accesses although
+-** none of the processors use it. There is a strong ordered bit that is
+-** set in the O-bit of the page directory entry. Operating systems that
+-** can not tolerate out of order accesses should set this bit when mapping
+-** pages. The O-bit of the PSW should also be set to 1 (I don't believe any
+-** of the processor implemented the PSW O-bit). The PCX-W ERS states that
+-** the TLB O-bit is not implemented so the page directory does not need to
+-** have the O-bit set when mapping pages (section 3.1). This section also
+-** states that the PSW Y, Z, G, and O bits are not implemented.
+-** So it looks like nothing needs to be done for parisc-linux (yet).
+-** (thanks to chada for the above comment -ggg)

+- * read_barrier_depends - Flush all pending reads that subsequents reads
+- * depend on.
+- *
+- * No data-dependent reads from memory-like regions are ever reordered
+- * over this barrier. All reads preceding this primitive are guaranteed
+- * to access memory (but not necessarily other CPUs' caches) before any
+- * reads following this primitive that depend on the data return by
+- * any of the preceding reads. This primitive is much lighter weight than
+- * rmb() on most CPUs, and is never heavier weight than is
+- * rmb().
+- *
+- * These ordering constraints are respected by both the local CPU
+- * and the compiler.
+- *
+- * Ordering is not guaranteed by anything other than these primitives,
+- * not even by data dependencies. See the documentation for
+- * memory_barrier() for examples and URLs to more information.
+- *
+- * For example, the following code would force ordering (the initial
+- * value of "a" is zero, "b" is one, and "p" is "&a"):
+- *
+- * <programlisting>
+- * CPU 0 CPU 1
+- *
+- * b = 2;
+- * memory_barrier();
+- * p = &b; q = p;
+- * read_barrier_depends();
+- * d = *q;
+- * </programlisting>
+- *
+- * because the read of "*q" depends on the read of "p" and these
+- * two reads are separated by a read_barrier_depends(). However,
+- * the following code, with the same initial values for "a" and "b":
+- *
+- * <programlisting>
+- * CPU 0 CPU 1
+- *
+- * a = 2;
+- * memory_barrier();
+- * b = 3; y = b;
+- * read_barrier_depends();
+- * x = a;
+- * </programlisting>
+- *
+- * does not enforce ordering, since there is no data dependency between
+- * the read of "a" and the read of "b". Therefore, on some CPUs, such
+- * as Alpha, "y" could be set to 3 and "x" to 0. Use rmb()
+- * in cases like this where there are no data dependencies.

++ * 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.

+Subject: KEYS: Fix keyring ref leak in join_session_keyring()
+
+This fixes CVE-2016-0728.
+
+If a thread is asked to join as a session keyring the keyring that's already
+set as its session, we leak a keyring reference.
+
+This can be tested with the following program:
+
+ #include <stddef.h>
+ #include <stdio.h>
+ #include <sys/types.h>
+ #include <keyutils.h>
+
+ int main(int argc, const char *argv[])
+ {
+ int i = 0;
+ key_serial_t serial;
+
+ serial = keyctl(KEYCTL_JOIN_SESSION_KEYRING,
+ "leaked-keyring");
+ if (serial < 0) {
+ perror("keyctl");
+ return -1;
+ }
+
+ if (keyctl(KEYCTL_SETPERM, serial,
+ KEY_POS_ALL | KEY_USR_ALL) < 0) {
+ perror("keyctl");
+ return -1;
+ }
+
+ for (i = 0; i < 100; i++) {
+ serial = keyctl(KEYCTL_JOIN_SESSION_KEYRING,
+ "leaked-keyring");
+ if (serial < 0) {
+ perror("keyctl");
+ return -1;
+ }
+ }
+
+ return 0;
+ }
+
+If, after the program has run, there something like the following line in
+/proc/keys:
+
+3f3d898f I--Q--- 100 perm 3f3f0000 0 0 keyring leaked-keyring: empty
+
+with a usage count of 100 * the number of times the program has been run,
+then the kernel is malfunctioning. If leaked-keyring has zero usages or
+has been garbage collected, then the problem is fixed.

-Subject: KEYS: Fix keyring ref leak in join_session_keyring()
-
-This fixes CVE-2016-0728.
-
-If a thread is asked to join as a session keyring the keyring that's already
-set as its session, we leak a keyring reference.
-
-This can be tested with the following program:
-
- #include <stddef.h>
- #include <stdio.h>
- #include <sys/types.h>
- #include <keyutils.h>
-
- int main(int argc, const char *argv[])
- {
- int i = 0;
- key_serial_t serial;
-
- serial = keyctl(KEYCTL_JOIN_SESSION_KEYRING,
- "leaked-keyring");
- if (serial < 0) {
- perror("keyctl");
- return -1;
- }
-
- if (keyctl(KEYCTL_SETPERM, serial,
- KEY_POS_ALL | KEY_USR_ALL) < 0) {
- perror("keyctl");
- return -1;
- }
-
- for (i = 0; i < 100; i++) {
- serial = keyctl(KEYCTL_JOIN_SESSION_KEYRING,
- "leaked-keyring");
- if (serial < 0) {
- perror("keyctl");
- return -1;
- }
- }
-
- return 0;
- }
-
-If, after the program has run, there something like the following line in
-/proc/keys:
-
-3f3d898f I--Q--- 100 perm 3f3f0000 0 0 keyring leaked-keyring: empty
-
-with a usage count of 100 * the number of times the program has been run,
-then the kernel is malfunctioning. If leaked-keyring has zero usages or
-has been garbage collected, then the problem is fixed.

++ * The 32-bit x86 assembler in binutils 2.26 will generate R_386_GOT32X

++ *
++ * If the compressed x86 kernel is relocatable at run-time, it should be

++ * optimal than R_386_RELATIVE. But the x86 kernel fails to properly handle
++ * R_386_32 relocations when relocating the kernel. To generate
