Via u32_change(), TCA_U32_SEL has an unspecified type in the netlink policy, so max length isn't enforced, only minimum. This means nkeys (from userspace) was being trusted without checking the actual size of nla_len(), which could lead to a memory over-read, and ultimately an exposure via a call to u32_dump().

Merge tag 'libnvdimm-for-4.19_dax-memory-failure' of gitolite.kernel.org:pub/scm/linux/kernel/git/nvdimm/nvdimm Pull libnvdimm memory-failure update from Dave Jiang: "As it stands, memory_failure() gets thoroughly confused by dev_pagemap backed mappings. The recovery code has specific enabling for several possible page states and needs new enabling to handle poison in dax mappings. In order to support reliable reverse mapping of user space addresses: 1/ Add new locking in the memory_failure() rmap path to prevent races that would typically be handled by the page lock. 2/ Since dev_pagemap pages are hidden from the page allocator and the "compound page" accounting machinery, add a mechanism to determine the size of the mapping that encompasses a given poisoned pfn. 3/ Given pmem errors can be repaired, change the speculatively accessed poison protection, mce_unmap_kpfn(), to be reversible and otherwise allow ongoing access from the kernel. A side effect of this enabling is that MADV_HWPOISON becomes usable for dax mappings, however the primary motivation is to allow the system to survive userspace consumption of hardware-poison via dax. Specifically the current behavior is: mce: Uncorrected hardware memory error in user-access at af34214200 {1}[Hardware Error]: It has been corrected by h/w and requires no further action mce: [Hardware Error]: Machine check events logged {1}[Hardware Error]: event severity: corrected Memory failure: 0xaf34214: reserved kernel page still referenced by 1 users [..] Memory failure: 0xaf34214: recovery action for reserved kernel page: Failed mce: Memory error not recovered <reboot> ...and with these changes: Injecting memory failure for pfn 0x20cb00 at process virtual address 0x7f763dd00000 Memory failure: 0x20cb00: Killing dax-pmd:5421 due to hardware memory corruption Memory failure: 0x20cb00: recovery action for dax page: Recovered Given all the cross dependencies I propose taking this through nvdimm.git with acks from Naoya, x86/core, x86/RAS, and of course dax folks" * tag 'libnvdimm-for-4.19_dax-memory-failure' of gitolite.kernel.org:pub/scm/linux/kernel/git/nvdimm/nvdimm: libnvdimm, pmem: Restore page attributes when clearing errors x86/memory_failure: Introduce {set, clear}_mce_nospec() x86/mm/pat: Prepare {reserve, free}_memtype() for "decoy" addresses mm, memory_failure: Teach memory_failure() about dev_pagemap pages filesystem-dax: Introduce dax_lock_mapping_entry() mm, memory_failure: Collect mapping size in collect_procs() mm, madvise_inject_error: Let memory_failure() optionally take a page reference mm, dev_pagemap: Do not clear ->mapping on final put mm, madvise_inject_error: Disable MADV_SOFT_OFFLINE for ZONE_DEVICE pages filesystem-dax: Set page->index device-dax: Set page->index device-dax: Enable page_mapping() device-dax: Convert to vmf_insert_mixed and vm_fault_t

qlge_fix_features() is not supposed to modify hardware or driver state, rather it is supposed to only fix requested fetures bits. Currently qlge_fix_features() also goes for interface down and up unnecessarily if there is not even any change in features set. This patch changes/fixes following - 1) Move reload of interface or device re-config from qlge_fix_features() to qlge_set_features(). 2) Reload of interface in qlge_set_features() only if relevant feature bit (NETIF_F_HW_VLAN_CTAG_RX) is changed. 3) Get rid of qlge_fix_features() since driver is not really required to fix any features bit.

macb_reset_hw() is called from macb_close() and indirectly from macb_open(). macb_reset_hw() zeroes the NCR register, including the MPE (Management Port Enable) bit. This will prevent accessing any other PHYs for other Ethernet MACs on the MDIO bus, which remains registered at macb_reset_hw() time, until macb_init_hw() is called from macb_open() which sets the MPE bit again. I.e. currently the MDIO bus has a short disruption at open time and is disabled at close time until the interface is opened again. Fix that by only touching the RE and TE bits when enabling and disabling RX/TX. v2: Make macb_init_hw() NCR write a single statement.

When a bridge device is removed, the VLANs are flushed from each configured port. This causes the ports to decrement the reference count on the associated FIDs (filtering identifier). If the reference count of a FID is 1 and it has a RIF (router interface), then this RIF is destroyed. However, if no port is member in the VLAN for which a RIF exists, then the RIF will continue to exist after the removal of the bridge. To reproduce: # ip link add name br0 type bridge vlan_filtering 1 # ip link set dev swp1 master br0 # ip link add link br0 name br0.10 type vlan id 10 # ip address add 192.0.2.0/24 dev br0.10 # ip link del dev br0 The RIF associated with br0.10 continues to exist. Fix this by iterating over all the bridge device uppers when it is destroyed and take care of destroying their RIFs.

This is not normally noticeable, but repeated forks are unnecessarily expensive because they repeatedly dirty the parent page tables during the page table copy operation. It's trivial to just avoid write protecting the page table entry if it was already not writable. This patch was inspired by https://bugzilla.kernel.org/show_bug.cgi?id=200447 which points to an ancient "waste time re-doing fork" issue in the presence of lots of signals. That bug was fixed by Eric Biederman's signal handling series culminating in commit c3ad2c3b ("signal: Don't restart fork when signals come in"), but the unnecessary work for repeated forks is still work just fixing, particularly since the fix is trivial.

At the point where r is being checked for different values, r is always going to be equal to 2 as the previous if statements jump to end or end1 if r is not 2. Hence the assignment to err can be simplified to just err an assignment without any checks on the value or r.

Thanks for your work in this area. I still remember the first linux storage summit we did in Vancouver 2001, Tejun was invited to talk about his libata error handling work. Before that, it was basically a crap shoot if we recovered properly or not... A lot of water has flown under the bridge since then! Here's an "official" patch. Linus, can you apply it?

Earlier used to post the current command without checking queue full after backlog submissions. So, post the current command only after confirming the space in queue after backlog submissions. Maintain host write index instead of reading device registers to get the next free slot to post the command. Return -ENOSPC in queue full case.

This patch fixes sleep-in-atomic bugs in AES-CBC and AES-XTS VMX implementations. The problem is that the blkcipher_* functions should not be called in atomic context. The bugs can be reproduced via the AF_ALG interface by trying to encrypt/decrypt sufficiently large buffers (at least 64 KiB) using the VMX implementations of 'cbc(aes)' or 'xts(aes)'. Such operations then trigger BUG in crypto_yield(): [ 891.863680] BUG: sleeping function called from invalid context at include/crypto/algapi.h:424 [ 891.864622] in_atomic(): 1, irqs_disabled(): 0, pid: 12347, name: kcapi-enc [ 891.864739] 1 lock held by kcapi-enc/12347: [ 891.864811] #0: 00000000f5d42c46 (sk_lock-AF_ALG){+.+.}, at: skcipher_recvmsg+0x50/0x530 [ 891.865076] CPU: 5 PID: 12347 Comm: kcapi-enc Not tainted 4.19.0-0.rc0.git3.1.fc30.ppc64le #1 [ 891.865251] Call Trace: [ 891.865340] [c0000003387578c0] [c000000000d67ea4] dump_stack+0xe8/0x164 (unreliable) [ 891.865511] [c000000338757910] [c000000000172a58] ___might_sleep+0x2f8/0x310 [ 891.865679] [c000000338757990] [c0000000006bff74] blkcipher_walk_done+0x374/0x4a0 [ 891.865825] [c0000003387579e0] [d000000007e73e70] p8_aes_cbc_encrypt+0x1c8/0x260 [vmx_crypto] [ 891.865993] [c000000338757ad0] [c0000000006c0ee0] skcipher_encrypt_blkcipher+0x60/0x80 [ 891.866128] [c000000338757b10] [c0000000006ec504] skcipher_recvmsg+0x424/0x530 [ 891.866283] [c000000338757bd0] [c000000000b00654] sock_recvmsg+0x74/0xa0 [ 891.866403] [c000000338757c10] [c000000000b00f64] ___sys_recvmsg+0xf4/0x2f0 [ 891.866515] [c000000338757d90] [c000000000b02bb8] __sys_recvmsg+0x68/0xe0 [ 891.866631] [c000000338757e30] [c00000000000bbe4] system_call+0x5c/0x70 Fixes: 8c755ace ("crypto: vmx - Adding CBC routines for VMX module") Fixes: c07f5d3d ("crypto: vmx - Adding support for XTS") Cc: stable@vger.kernel.org Signed-off-by: NOndrej Mosnacek <omosnace@redhat.com> Signed-off-by: NHerbert Xu <herbert@gondor.apana.org.au>

Commit 71e52c27 ("crypto: arm64/aes-ce-gcm - operate on two input blocks at a time") modified the granularity at which the AES/GCM code processes its input to allow subsequent changes to be applied that improve performance by using aggregation to process multiple input blocks at once. For this reason, it doubled the algorithm's 'chunksize' property to 2 x AES_BLOCK_SIZE, but retained the non-SIMD fallback path that processes a single block at a time. In some cases, this violates the skcipher scatterwalk API, by calling skcipher_walk_done() with a non-zero residue value for a chunk that is expected to be handled in its entirety. This results in a WARN_ON() to be hit by the TLS self test code, but is likely to break other user cases as well. Unfortunately, none of the current test cases exercises this exact code path at the moment. Fixes: 71e52c27 ("crypto: arm64/aes-ce-gcm - operate on two ...")

A regression was reported bisecting to 1476db2d "Move HashKey computation from stack to gcm_context". That diff moved HashKey computation from the stack, which was explicitly aligned in the asm, to a struct provided from the C code, depending on AESNI_ALIGN_ATTR for alignment. It appears some compilers may not align this struct correctly, resulting in a crash on the movdqa instruction when attempting to encrypt or decrypt data. Fix by using unaligned loads for the HashKeys. On modern hardware there is no perf difference between the unaligned and aligned loads. All other accesses to gcm_context_data already use unaligned loads.

ARMv8.2 specifies special instructions for the SM3 cryptographic hash and the SM4 symmetric cipher. While it is unlikely that a core would implement one and not the other, we should only use SM4 instructions if the SM4 CPU feature bit is set, and we currently check the SM3 feature bit instead. So fix that. Fixes: e99ce921 ("crypto: arm64 - add support for SM4...")

Jeff Kirsher says: ==================== Intel Wired LAN Driver Updates 2018-08-24 This series contains fixes to e1000, igb, ixgb, ixgbe and i40e. YueHaibing from Huawei provides a change to use dma_zalloc_coherent() instead of calls to allocator followed by a memset for ixgb. Bo Chen provides a couple of fixes for e1000, first by adding a check to prevent a NULL pointer dereference. The second change is to clean up a possible resource leak on old transmit and receive rings when the device is not up. Jesus fixes an issue in the usage of an advanced transmit context descriptor for retrieving the timestamp of a packet for AF_PACKET if the IGB_TX_FLAGS_VLAN is not set in igb. Jia-Ju Bai provides several patches which replace GFP_ATOMIC with GFP_KERNEL, when using kzalloc() and kcalloc() which is not necessary. Also found an instance of mdelay() call which could be replaced with msleep(). Tony fixes ixgbe to allow MTU changes with XDP, by adding checks to ensure only supported values and return -EINVAL for when it is not supported. Sebastian fixed an issue that was not clearing VF mailbox memory and ensure queues are re-enabled correctly. Martyna fixes a transmit timeout when DCB is configured when bringing up an interface. Jake fixes a previous commit which accidentally reversed the check of the data pointer, so we can accurately count the size of the stats. ==================== Signed-off-by: NDavid S.
