Subject: [PATCH] seccomp: allow sched_setscheduler() with SCHED_IDLE policy
|
||||
MIME-Version: 1.0
|
||||
Content-Type: text/plain; charset=UTF-8
|
||||
Content-Transfer-Encoding: 8bit
|
||||
|
||||
Current and upcoming mesa releases rely on a shader disk cash. It uses
|
||||
a thread job queue with low priority, set with
|
||||
sched_setscheduler(SCHED_IDLE). However, that syscall is rejected by
|
||||
the "resourcecontrol" seccomp qemu filter.
|
||||
|
||||
Since it should be safe to allow lowering thread priority, let's allow
|
||||
scheduling thread to idle policy.

Newer binutils (>= 2.31) will emit PLT32 relocs for call/jmp
|
||||
instructions on x86_64 in some cases, instead of PC32 relocs
|
||||
as before. This can only be done because on x86-64 the PLT
|
||||
doesn't need any special setup, and in turn this means that
|
||||
for post-processing/after-link purposes PLT32 and PC32 relocs
|
||||
can be handled the same. elf2efi simply ignores all PC-relative
|
||||
relocs (as the code is already fully final for them) and PLT32
|
||||
is one of them, so add it to the list.
|
||||
|
||||
(Otherwise an "Unrecognized relocation type 4" error occurs
|
||||
when building some of the EFI images for IPXE).
