As we are about to need to access system registers from the HYP code based on their internal encoding, move the direct sysreg accessors to a common include file, with a VHE-specific guard. No functionnal change. Acked-by: Mark Rutland <mark.rutland@arm.com> Signed-off-by: Marc Zyngier <maz@kernel.org>

Instead of handling the "PC rollback on SError during HVC" at EL1 (which requires disclosing PC to a potentially untrusted kernel), let's move this fixup to ... fixup_guest_exit(), which is where we do all fixups. Isn't that neat? Signed-off-by: Marc Zyngier <maz@kernel.org>

In an effort to remove the vcpu PC manipulations from EL1 on nVHE systems, move kvm_skip_instr() to be HYP-specific. EL1's intent to increment PC post emulation is now signalled via a flag in the vcpu structure. Signed-off-by: Marc Zyngier <maz@kernel.org>

There is no need to feed the result of kvm_vcpu_trap_il_is32bit() to kvm_skip_instr(), as only AArch32 has a variable length ISA, and this helper can equally be called from kvm_skip_instr32(), reducing the complexity at all the call sites.

On SMC trap, the prefered return address is set to that of the SMC instruction itself. It is thus wrong to try and roll it back when an SError occurs while trapping on SMC. It is still necessary on HVC though, as HVC doesn't cause a trap, and sets ELR to returning *after* the HVC. It also became apparent that there is no 16bit encoding for an AArch32 HVC instruction, meaning that the displacement is always 4 bytes, no matter what the ISA is. Take this opportunity to simplify it. Acked-by: Mark Rutland <mark.rutland@arm.com> Signed-off-by: Marc Zyngier <maz@kernel.org>

Obviously, this will cause an out-of-bounds read, because we can > access a smaller vc_font.data with a larger vc_font.height. Further there was only one user ever. - Android's loadfont, busybox and console-tools only ever use OP_GET and OP_SET - fbset documentation only mentions the kernel cmdline font: option, not anything else. - systemd used OP_COPY before release 232 published in Nov 2016 Now unfortunately the crucial report seems to have gone down with gmane, and the commit message doesn't say much. But the pull request hints at OP_COPY being broken https://github.com/systemd/systemd/pull/3651 So in other words, this never worked, and the only project which foolishly every tried to use it, realized that rather quickly too. Instead of trying to fix security issues here on dead code by adding missing checks, fix the entire thing by removing the functionality. Note that systemd code using the OP_COPY function ignored the return value, so it doesn't matter what we're doing here really - just in case a lone server somewhere happens to be extremely unlucky and running an affected old version of systemd. The relevant code from font_copy_to_all_vcs() in systemd was: /* copy font from active VT, where the font was uploaded to */ cfo.op = KD_FONT_OP_COPY; cfo.height = vcs.v_active-1; /* tty1 == index 0 */ (void) ioctl(vcfd, KDFONTOP, &cfo); Note this just disables the ioctl, garbage collecting the now unused callbacks is left for -next. v2: Tetsuo found the old mail, which allowed me to find it on another archive.

Merge procfs splice read fixes from Christoph Hellwig: "Greg reported a problem due to the fact that Android tests use procfs files to test splice, which stopped working with the changes for set_fs() removal. This series adds read_iter support for seq_file, and uses those for various proc files using seq_file to restore splice read support" [ Side note: Christoph initially had a scripted "move everything over" patch, which looks fine, but I personally would prefer us to actively discourage splice() on random files. So this does just the minimal basic core set of proc file op conversions. For completeness, and in case people care, that script was sed -i -e 's/\.proc_read\(\s*=\s*\)seq_read/\.proc_read_iter\1seq_read_iter/g' but I'll wait and see if somebody has a strong argument for using splice on random small /proc files before I'd run it on the whole kernel. - Linus ] * emailed patches from Christoph Hellwig <hch@lst.de>: proc "seq files": switch to ->read_iter proc "single files": switch to ->read_iter proc/stat: switch to ->read_iter proc/cpuinfo: switch to ->read_iter proc: wire up generic_file_splice_read for iter ops seq_file: add seq_read_iter

Gratian managed to trigger the BUG_ON(!newowner) in fixup_pi_state_owner(). This is one possible chain of events leading to this: Task Prio Operation T1 120 lock(F) T2 120 lock(F) -> blocks (top waiter) T3 50 (RT) lock(F) -> boosts T1 and blocks (new top waiter) XX timeout/ -> wakes T2 signal T1 50 unlock(F) -> wakes T3 (rtmutex->owner == NULL, waiter bit is set) T2 120 cleanup -> try_to_take_mutex() fails because T3 is the top waiter and the lower priority T2 cannot steal the lock. -> fixup_pi_state_owner() sees newowner == NULL -> BUG_ON() The comment states that this is invalid and rt_mutex_real_owner() must return a non NULL owner when the trylock failed, but in case of a queued and woken up waiter rt_mutex_real_owner() == NULL is a valid transient state. The higher priority waiter has simply not yet managed to take over the rtmutex. The BUG_ON() is therefore wrong and this is just another retry condition in fixup_pi_state_owner(). Drop the locks, so that T3 can make progress, and then try the fixup again. Gratian provided a great analysis, traces and a reproducer. The analysis is to the point, but it confused the hell out of that tglx dude who had to page in all the futex horrors again. Condensed version is above.

As shown through runtime testing, the "filename" allocation is not always freed in perf_event_parse_addr_filter(). There are three possible ways that this could happen: - It could be allocated twice on subsequent iterations through the loop, - or leaked on the success path, - or on the failure path. Clean up the code flow to make it obvious that 'filename' is always freed in the reallocation path and in the two return paths as well. We rely on the fact that kfree(NULL) is NOP and filename is initialized with NULL. This fixes the leak. No other side effects expected.

Pull drm fixes from Dave Airlie: "It's Friday here so that means another installment of drm fixes to distract you from the counting process. Changes all over the place, the amdgpu changes contain support for a new GPU that is close to current one already in the tree (Green Sardine) so it shouldn't have much side effects. Otherwise imx has a few cleanup patches and fixes, amdgpu and i915 have around the usual smattering of fixes, fonts got constified, and vc4/panfrost has some minor fixes. All in all a fairly regular rc3. We have an outstanding nouveau regression, but the author is looking into the fix, so should be here next week. I now return you to counting. fonts: - constify font structures. MAINTAINERS: - Fix path for amdgpu power management amdgpu: - Add support for more navi1x SKUs - Fix for suspend on CI dGPUs - VCN DPG fix for Picasso - Sienna Cichlid fixes - Polaris DPM fix - Add support for Green Sardine amdkfd: - Fix an allocation failure check i915: - Fix set domain's cache coherency - Fixes around breadcrumbs - Fix encoder lookup during PSR atomic - Hold onto an explicit ref to i915_vma_work.pinned - gvt: HWSP reset handling fix - gvt: flush workaround - gvt: vGPU context pin/unpin - gvt: mmio cmd access fix for bxt/apl imx: - drop unused functions and callbacks - reuse imx_drm_encoder_parse_of - spinlock rework - memory leak fix - minor cleanups vc4: - resource cleanup fix panfrost: - madvise/shrinker fix" * tag 'drm-fixes-2020-11-06-1' of git://anongit.freedesktop.org/drm/drm: (55 commits) drm/amdgpu/display: remove DRM_AMD_DC_GREEN_SARDINE drm/amd/display: Add green_sardine support to DM drm/amd/display: Add green_sardine support to DC drm/amdgpu: enable vcn support for green_sardine (v2) drm/amdgpu: enable green_sardine_asd.bin loading (v2) drm/amdgpu/sdma: add sdma engine support for green_sardine (v2) drm/amdgpu: add gfx support for green_sardine (v2) drm/amdgpu: add soc15 common ip block support for green_sardine (v3) drm/amdgpu: add green_sardine support for gpu_info and ip block setting (v2) drm/amdgpu: add Green_Sardine APU flag drm/amdgpu: resolved ASD loading issue on sienna amdkfd: Check kvmalloc return before memcpy drm/amdgpu: update golden setting for sienna_cichlid amd/amdgpu: Disable VCN DPG mode for Picasso drm/amdgpu/swsmu: remove duplicate call to smu_set_default_dpm_table drm/i915: Hold onto an explicit ref to i915_vma_work.pinned drm/i915/gt: Flush xcs before tgl breadcrumbs drm/i915/gt: Expose more parameters for emitting writes into the ring drm/i915: Fix encoder lookup during PSR atomic check drm/i915/gt: Use the local HWSP offset during submission ...
