[ Upstream commit 3f7352bf ] x86 has variable length encoding. x86 JIT compiler is trying to pick the shortest encoding for given bpf instruction. While doing so the jump targets are changing, so JIT is doing multiple passes over the program. Typical program needs 3 passes. Some very short programs converge with 2 passes. Large programs may need 4 or 5. But specially crafted bpf programs may hit the pass limit and if the program converges on the last iteration the JIT compiler will be producing an image full of 'int 3' insns. Fix this corner case by doing final iteration over bpf program. Fixes: 0a14842f ("net: filter: Just In Time compiler for x86-64") Reported-by:

[ Upstream commit d66bf7dd ] The code in __netdev_upper_dev_link() has an over-stringent loop detection logic that actually prevents valid configurations from working correctly. In particular, the logic returns an error if an upper device is already in the list of all upper devices for a given dev. This particular check seems to be a overzealous as it disallows perfectly valid configurations. For example: # ip l a link eth0 name eth0.10 type vlan id 10 # ip l a dev br0 typ bridge # ip l s eth0.10 master br0 # ip l s eth0 master br0 <--- Will fail If you switch the last two commands (add eth0 first), then both will succeed. If after that, you remove eth0 and try to re-add it, it will fail! It appears to be enough to simply check adj_list to keeps things safe. I've tried stacking multiple devices multiple times in all different combinations, and either rx_handler registration prevented the stacking of the device linking cought the error. Signed-off-by:

commit dc48e56d upstream. exit_aio() currently serializes killing io contexts. Each context killing ends up having to do percpu_ref_kill(), which in turns has to wait for an RCU grace period. This can take a long time, depending on the number of contexts. And there's no point in doing them serially, when we could be waiting for all of them in one fell swoop. This patches makes my fio thread offload test case exit 0.2s instead of almost 6s. Reviewed-by:

commit 45002267 upstream. Crush temporary buffers are allocated as per replica size configured by the user. When there are more final osds (to be selected as per rule) than the replicas, buffer overlaps and it causes crash. Now, it ensures that at most num-rep osds are selected even if more number of osds are allowed by the rule.

commit 56ccc112 upstream. A recent change removed the need for locking around writing to "sync_action" (and various other places), but introduced a subtle race. When e.g. setting 'reshape' on a 'frozen' array, the 'frozen' flag is cleared before 'reshape' is set, so the md thread can get in and start trying recovery - which isn't wanted. So instead of clearing MD_RECOVERY_FROZEN for any command except 'frozen', only clear it when each specific command is parsed. This allows the handling of 'reshape' to clear the bit while a lock is held. Also remove some places where we set MD_RECOVERY_NEEDED, as it is always set on non-error exit of the function.

commit 1e70897d upstream. The PWM hardware on Pistachio platform has a maximum timebase steps value to 255. To fix it, let's introduce a compatible-specific data structure to contain the SoC-specific details and use it to specify a maximum timebase. Also, let's limit the minimum timebase to 16 steps, to allow a sane range of duty cycle steps. Fixes: 277bb6a2 ("pwm: Imagination Technologies PWM DAC driver") Signed-off-by:

commit 98fb1ffd upstream. Block drivers are responsible for calling flush_dcache_page() on each BIO request. This operation keeps the I$ coherent with the D$ on architectures that don't have hardware coherency support. Without this flush, random crashes are seen when executing user programs from an ext4 filesystem backed by a ubiblock device. This patch is based on the change implemented in commit 2d4dc890 ("block: add helpers to run flush_dcache_page() against a bio and a request's pages").

commit 161f873b upstream. We used to read file_handle twice. Once to get the amount of extra bytes, and once to fetch the entire structure. This may be problematic since we do size verifications only after the first read, so if the number of extra bytes changes in userspace between the first and second calls, we'll have an incoherent view of file_handle. Instead, read the constant size once, and copy that over to the final structure without having to re-read it again. Signed-off-by:

commit 15b94a69 upstream. dm-multipath accepts 0 path mapping. # echo '0 2097152 multipath 0 0 0 0' | dmsetup create newdev Such a mapping can be used to release underlying devices while still holding requests in its queue until working paths come back. However, once the multipath device is created over blk-mq devices, it rejects reloading of 0 path mapping: # echo '0 2097152 multipath 0 0 1 1 queue-length 0 1 1 /dev/sda 1' \ | dmsetup create mpath1 # echo '0 2097152 multipath 0 0 0 0' | dmsetup load mpath1 device-mapper: reload ioctl on mpath1 failed: Invalid argument Command failed With following kernel message: device-mapper: ioctl: can't change device type after initial table load. DM tries to inherit the current table type using dm_table_set_type() but it doesn't work as expected because of unnecessary check about whether the target type is hybrid or not. Hybrid type is for targets that work as either request-based or bio-based and not required for blk-mq or non blk-mq checking.

commit 1c220c69 upstream. dm_merge_bvec() was originally added in f6fccb ("dm: introduce merge_bvec_fn"). In that commit a value in sectors is converted to bytes using << 9, and then assigned to an int. This code made assumptions about the value of BIO_MAX_SECTORS. A later commit 148e51 ("dm: improve documentation and code clarity in dm_merge_bvec") was meant to have no functional change but it removed the use of BIO_MAX_SECTORS in favor of using queue_max_sectors(). At this point the cast from sector_t to int resulted in a zero value. The fallout being dm_merge_bvec() would only allow a single page to be added to a bio. This interim fix is minimal for the benefit of stable@ because the more comprehensive cleanup of passing a sector_t to all DM targets' merge function will impact quite a few DM targets.

commit b9a5e5e1 upstream. Since acpi_reserve_resources() is defined as a device_initcall(), there's no guarantee that it will be executed in the right order with respect to the rest of the ACPI initialization code. On some systems this leads to breakage if, for example, the address range that should be reserved for the ACPI fixed registers is given to the PCI host bridge instead if the race is won by the wrong code path. Fix this by turning acpi_reserve_resources() into a void function and calling it directly from within the ACPI initialization sequence. Reported-and-tested-by:

commit 620b1550 upstream. Commit 46490b57 ("MIPS: kernel: elf: Improve the overall ABI and FPU mode checks") reworked the ELF FP ABI mode selection logic, but when CONFIG_MIPS_O32_FP64_SUPPORT is enabled it breaks the use of binaries which have no PT_MIPS_ABIFLAGS program header & associated .MIPS.abiflags section. A default mode is selected based upon whether the ELF contains MIPS32 or MIPS64 code, but that selection is made in arch_elf_pt_proc. arch_elf_pt_proc only executes when a PT_MIPS_ABIFLAGS program header is found. If one is not found then arch_elf_pt_proc is never called, and no default overall_fp_mode value is selected. When arch_check_elf is called, both abi0 & abi1 are MIPS_ABI_FP_UNKNOWN which leads to both prog_req & interp_req being set to none_req. none_req matches none of the conditions for mode selection at the end of arch_check_elf, so overall_fp_mode is left untouched. Finally once mips_set_personality_fp is called the BUG() in the default case is then hit & the kernel likely panics. Fix this by moving the selection of a default overall mode to the start of arch_check_elf, which runs once per ELF executed regardless of whether it has a PT_MIPS_ABIFLAGS program header.

commit 5006c105 upstream. This reverts commit 3a61e975. The Logitech TK820 seems to be affected by a firmware bug which delays the sending of the keys (pressed, or released, which triggers a key-repeat) while holding fingers on the touch sensor. This behavior can be observed while using the mouse emulation mode if the user moves the finger while typing (highly improbable though). Holding the finger still while in the mouse emulation mode does not trigger the key repeat problem. So better keep things in their previous state to not have to explain users that the new key-repeat bug they see is a "feature". Furthermore, I noticed that I disabled the media keys whith this patch. Sorry, my bad. I think it is best to revert the patch, in all the current versions it has been shipped. Signed-off-by:

commit a8115776 upstream. The variable "sector" in "raid0_make_request()" was improperly updated by a call to "sector_div()" which modifies its first argument in place. Commit 47d68979 restored this variable after the call for later re-use. Unfortunetly the restore was done after the referenced variable "bio" was advanced. This lead to the original value and the restored value being different. Here we move this line to the proper place. One observed side effect of this bug was discarding a file though unlinking would cause an unrelated file's contents to be discarded. Signed-off-by:

commit 5c1ac56b upstream. In function dmi_present(), dmi_walk_early() calls dmi_table(), which calls dmi_decode(), which ultimately calls dmi_save_uuid(). This last function makes a decision based on the value of global variable dmi_ver. The problem is that this variable is set right _after_ dmi_walk_early() returns. So dmi_save_uuid() always sees dmi_ver == 0 regardless of the actual version implemented. This causes /sys/class/dmi/id/product_uuid to always use the old ordering even on systems implementing DMI/SMBIOS 2.6 or later, which should use the new ordering. This is broken since kernel v3.8 for legacy DMI implementations and since kernel v3.10 for SMBIOS 2 implementations. SMBIOS 3 implementations with the 64-bit entry point are not affected. The first breakage does not matter much as in practice legacy DMI implementations are always for versions older than 2.6, which is when the UUID ordering changed. The second breakage is more problematic as it affects the vast majority of x86 systems manufactured since 2009. Signed-off-by:

commit 9507271d upstream. In an environment where the KDC is running Active Directory, the exported composite name field returned in the context could be large enough to span a page boundary. Attaching a scratch buffer to the decoding xdr_stream helps deal with those cases. The case where we saw this was actually due to behavior that's been fixed in newer gss-proxy versions, but we're fixing it here too. Signed-off-by:

commit ebe9cb3b upstream. If we find a non-confirmed openowner we jump to exit the function, but do not set an error value. Fix this by factoring out a helper to do the check and properly set the error from nfsd4_validate_stateid. Signed-off-by:
