2022-01-12net: ipa: fix atomic update in ipa_endpoint_replenish()Alex Elder
In ipa_endpoint_replenish(), if an error occurs when attempting to replenish a receive buffer, we just quit and try again later. In that case we increment the backlog count to reflect that the attempt was unsuccessful. Then, if the add_one flag was true we increment the backlog again. This second increment is not included in the backlog local variable though, and its value determines whether delayed work should be scheduled. This is a bug. Fix this by determining whether 1 or 2 should be added to the backlog before adding it in a atomic_add_return() call.

2022-01-12ref_tracker: use __GFP_NOFAIL more carefullyEric Dumazet
syzbot was able to trigger this warning from new_slab() /* * All existing users of the __GFP_NOFAIL are blockable, so warn * of any new users that actually require GFP_NOWAIT */ if (WARN_ON_ONCE(!can_direct_reclaim)) goto fail; Indeed, we should use __GFP_NOFAIL if direct reclaim is possible. Hopefully in the future we will be able to use SLAB_NOFAILSLAB option so that syzbot can benefit from full ref_tracker even in the presence of memory fault injections.

When removing multiple devices in a daisy-chain, each hotplug port's reset_lock may be acquired recursively. It's never the same lock, so the lockdep splat is a false positive. Because locks at the same hierarchy level are never acquired recursively, a per-level lockdep class is sufficient to fix the lockdep warning. The choice to use one lockdep subclass per pcie-hotplug controller in the path to the root-bus was made to conserve class keys because their number is limited and the complexity grows quadratically with number of keys according to Documentation/locking/lockdep-design.rst.

2022-01-12video: vga16fb: Only probe for EGA and VGA 16 color graphic cardsJavier Martinez Canillas
The vga16fb framebuffer driver only supports Enhanced Graphics Adapter (EGA) and Video Graphics Array (VGA) 16 color graphic cards. But it doesn't check if the adapter is one of those or if a VGA16 mode is used. This means that the driver will be probed even if a VESA BIOS Extensions (VBE) or Graphics Output Protocol (GOP) interface is used. This issue has been present for a long time but it was only exposed by commit d391c5827107 ("drivers/firmware: move x86 Generic System Framebuffers support") since the platform device registration to match the {vesa,efi}fb drivers is done later as a consequence of that change. All non-x86 architectures though treat orig_video_isVGA as a boolean so only do the supported video mode check for x86 and not for other arches.

There is no separate battery for the Elan controller resulting in a battery level report of 0% or 1% depending on whether a stylus has interacted with the screen.

'ipv4-fix-accidental-rto_onlink-flags-passed-to-ip_route_output_key_hash' Guillaume Nault says: ==================== ipv4: Fix accidental RTO_ONLINK flags passed to ip_route_output_key_hash() The IPv4 stack generally uses the last bit of ->flowi4_tos as a flag indicating link scope for route lookups (RTO_ONLINK). Therefore, we have to be careful when copying a TOS value to ->flowi4_tos. In particular, the ->tos field of IPv4 packets may have this bit set because of ECN. Also tunnel keys generally accept any user value for the tos. This series fixes several places where ->flowi4_tos was set from non-sanitised values and the flowi4 structure was later used by ip_route_output_key_hash(). Note that the IPv4 stack usually clears the RTO_ONLINK bit using RT_TOS(). However this macro is based on an obsolete interpretation of the old IPv4 TOS field (RFC 1349) and clears the three high order bits too. Since we don't need to clear these bits and since it doesn't make sense to clear only one of the ECN bits, this patch series uses INET_ECN_MASK instead.

2022-01-11module: add in-kernel support for decompressingDmitry Torokhov
Current scheme of having userspace decompress kernel modules before loading them into the kernel runs afoul of LoadPin security policy, as it loses link between the source of kernel module on the disk and binary blob that is being loaded into the kernel. To solve this issue let's implement decompression in kernel, so that we can pass a file descriptor of compressed module file into finit_module() which will keep LoadPin happy. To let userspace know what compression/decompression scheme kernel supports it will create /sys/module/compression attribute. kmod can read this attribute and decide if it can pass compressed file to finit_module(). New MODULE_INIT_COMPRESSED_DATA flag indicates that the kernel should attempt to decompress the data read from file descriptor prior to trying load the module. To simplify things kernel will only implement single decompression method matching compression method selected when generating modules. This patch implements gzip and xz; more can be added later, Signed-off-by: Dmitry Torokhov <dmitry.torokhov@gmail.com> Signed-off-by: Luis Chamberlain <mcgrof@kernel.org>
