[PATCH for-4.9.y 0/5] net/sched: init failure fixes

by Amit Pundir

Hi Greg, Kindly consider/review following net/sched fixes for stable 4.9.y. This patchset is a follow-up of upstream fix 87b60cfacf9f ("net_sched: fix error recovery at qdisc creation") cherry-picked on stable 4.9.y. It fix null pointer dereferences due to uninitialized timer (qdisc watchdog) or double frees due to ->destroy cleaning up a second time. Here is the original submission https://www.mail-archive.com/netdev@vger.kernel.org/msg186003.html Cherry-picked and build tested on Linux 4.9.116 for ARCH=arm/arm64. These fixes are applicable for stable 4.4.y kernel as well, but one of the patches needed a minor rebasing, so I'm resending this series for 4.4.y in a separate thread to avoid any confusion. Regards, Amit Pundir Nikolay Aleksandrov (5): sch_htb: fix crash on init failure sch_multiq: fix double free on init failure sch_hhf: fix null pointer dereference on init failure sch_netem: avoid null pointer deref on init failure sch_tbf: fix two null pointer dereferences on init failure net/sched/sch_hhf.c | 3 +++ net/sched/sch_htb.c | 5 +++-- net/sched/sch_multiq.c | 7 +------ net/sched/sch_netem.c | 4 ++-- net/sched/sch_tbf.c | 5 +++-- 5 files changed, 12 insertions(+), 12 deletions(-) -- 2.7.4

[PATCH v2] x86/entry/64: Remove %ebx handling from error_entry/exit

by Sarah Newman

commit b3681dd548d06deb2e1573890829dff4b15abf46 upstream. This version applies to v4.9. >From Andy Lutomirski, original author: error_entry and error_exit communicate the user vs kernel status of the frame using %ebx. This is unnecessary -- the information is in regs->cs. Just use regs->cs. This makes error_entry simpler and makes error_exit more robust. It also fixes a nasty bug. Before all the Spectre nonsense, The xen_failsafe_callback entry point returned like this: ALLOC_PT_GPREGS_ON_STACK SAVE_C_REGS SAVE_EXTRA_REGS ENCODE_FRAME_POINTER jmp error_exit And it did not go through error_entry. This was bogus: RBX contained garbage, and error_exit expected a flag in RBX. Fortunately, it generally contained *nonzero* garbage, so the correct code path was used. As part of the Spectre fixes, code was added to clear RBX to mitigate certain speculation attacks. Now, depending on kernel configuration, RBX got zeroed and, when running some Wine workloads, the kernel crashes. This was introduced by: commit 3ac6d8c787b8 ("x86/entry/64: Clear registers for exceptions/interrupts, to reduce speculation attack surface") With this patch applied, RBX is no longer needed as a flag, and the problem goes away. I suspect that malicious userspace could use this bug to crash the kernel even without the offending patch applied, though. [Historical note: I wrote this patch as a cleanup before I was aware of the bug it fixed.] [Note to stable maintainers: this should probably get applied to all kernels.] Cc: Brian Gerst <brgerst(a)gmail.com> Cc: Borislav Petkov <bp(a)alien8.de> Cc: Dominik Brodowski <linux(a)dominikbrodowski.net> Cc: Ingo Molnar <mingo(a)redhat.com> Cc: "H.

[patch 129/167] reiserfs: fix broken xattr handling (heap corruption, bad retval)

by akpm＠linux-foundation.org

From: Jann Horn <jannh(a)google.com> Subject: reiserfs: fix broken xattr handling (heap corruption, bad retval) This fixes the following issues: - When a buffer size is supplied to reiserfs_listxattr() such that each individual name fits, but the concatenation of all names doesn't fit, reiserfs_listxattr() overflows the supplied buffer. This leads to a kernel heap overflow (verified using KASAN) followed by an out-of-bounds usercopy and is therefore a security bug. - When a buffer size is supplied to reiserfs_listxattr() such that a name doesn't fit, -ERANGE should be returned. But reiserfs instead just truncates the list of names; I have verified that if the only xattr on a file has a longer name than the supplied buffer length, listxattr() incorrectly returns zero. With my patch applied, -ERANGE is returned in both cases and the memory corruption doesn't happen anymore. Credit for making me clean this code up a bit goes to Al Viro, who pointed out that the ->actor calling convention is suboptimal and should be changed.
