[ Upstream commit c1c2d774 ] In rare conditions like two stage OS installation, the ethtool's get_channels function may be called when the device is in D3 state, leading to uncorrectable PCI error.

[ Upstream commit 1838d6c6 ] When this driver is built as a module, I cannot rmmod it after insmoding it. This is because that this driver calls ravb_mdio_init() at the time of probe, and module->refcnt is incremented by alloc_mdio_bitbang() called after that. Therefore, even if ifup is not performed, the driver is in use and rmmod cannot be performed. $ lsmod Module Size Used by ravb 40960 1 $ rmmod ravb rmmod: ERROR: Module ravb is in use Call ravb_mdio_init() at open and free_mdio_bitbang() at close, thereby rmmod is possible in the ifdown state.

[ Upstream commit 1e105e6a ] Following bug was reported via irc: nft list ruleset set knock_candidates_ipv4 { type ipv4_addr . inet_service size 65535 elements = { 127.0.0.1 . 123, 127.0.0.1 . 123 } } .. udp dport 123 add @knock_candidates_ipv4 { ip saddr . 123 } udp dport 123 add @knock_candidates_ipv4 { ip saddr . udp dport } It should not have been possible to add a duplicate set entry. After some debugging it turned out that the problem is the immediate value (123) in the second-to-last rule. Concatenations use 32bit registers, i.e. the elements are 8 bytes each, not 6 and it turns out the kernel inserted inet firewall @knock_candidates_ipv4 element 0100007f ffff7b00 : 0 [end] element 0100007f 00007b00 : 0 [end] Note the non-zero upper bits of the first element. It turns out that nft_immediate doesn't zero the destination register, but this is needed when the length isn't a multiple of 4. Furthermore, the zeroing in nft_payload is broken. We can't use [len / 4] = 0 -- if len is a multiple of 4, index is off by one. Skip zeroing in this case and use a conditional instead of (len -1) / 4.

We would then not only skip our own OGM but erroneously also any other, following OGM in the aggregate. For another, we might receive an OGM aggregate which has our own OGM in a place other then the first one.

[ Upstream commit 303216e7 ] The gateway client code can try to optimize the delivery of DHCP packets to avoid broadcasting them through the whole mesh. But also transmissions to the client can be optimized by looking up the destination via the chaddr of the DHCP packet. But the chaddr is currently only done when chaddr is fully inside the non-paged area of the skbuff. Otherwise it will not be initialized and the unoptimized path should have been taken. But the implementation didn't handle this correctly. It didn't retrieve the correct chaddr but still tried to perform the TT lookup with this uninitialized memory.

commit 3c58f737 upstream. (scatter|gather)_data_area() need to flush dcache after writing data to or before reading data from a page in uio data area. The two routines are able to handle data transfer to/from such a page in fragments and flush the cache after each fragment was copied by calling the wrapper tcmu_flush_dcache_range(). That means: 1) flush_dcache_page() can be called multiple times for the same page. 2) Calling flush_dcache_page() indirectly using the wrapper does not make sense, because each call of the wrapper is for one single page only and the calling routine already has the correct page pointer. Change (scatter|gather)_data_area() such that, instead of calling tcmu_flush_dcache_range() before/after each memcpy, it now calls flush_dcache_page() before unmapping a page (when writing is complete for that page) or after mapping a page (when starting to read the page). After this change only calls to tcmu_flush_dcache_range() for addresses in vmalloc'ed command ring are left over. The patch was tested on ARM with kernel 4.19.118 and 5.7.2 Link: https://lore.kernel.org/r/20200618131632.32748-2-bstroesser@ts.fujitsu.comTested-by:

commit 8c4e0f21 upstream. 1) If remaining ring space before the end of the ring is smaller then the next cmd to write, tcmu writes a padding entry which fills the remaining space at the end of the ring. Then tcmu calls tcmu_flush_dcache_range() with the size of struct tcmu_cmd_entry as data length to flush. If the space filled by the padding was smaller then tcmu_cmd_entry, tcmu_flush_dcache_range() is called for an address range reaching behind the end of the vmalloc'ed ring. tcmu_flush_dcache_range() in a loop calls flush_dcache_page(virt_to_page(start)); for every page being part of the range. On x86 the line is optimized out by the compiler, as flush_dcache_page() is empty on x86. But I assume the above can cause trouble on other architectures that really have a flush_dcache_page(). For paddings only the header part of an entry is relevant due to alignment rules the header always fits in the remaining space, if padding is needed. So tcmu_flush_dcache_range() can safely be called with sizeof(entry->hdr) as the length here. 2) After it has written a command to cmd ring, tcmu calls tcmu_flush_dcache_range() using the size of a struct tcmu_cmd_entry as data length to flush. But if a command needs many iovecs, the real size of the command may be bigger then tcmu_cmd_entry, so a part of the written command is not flushed then.

commit 35556bed upstream. When calling into hid_map_usage(), the passed event code is blindly stored as is, even if it doesn't fit in the associated bitmap. This event code can come from a variety of sources, including devices masquerading as input devices, only a bit more "programmable". Instead of taking the event code at face value, check that it actually fits the corresponding bitmap, and if it doesn't: - spit out a warning so that we know which device is acting up - NULLify the bitmap pointer so that we catch unexpected uses Code paths that can make use of untrusted inputs can now check that the mapping was indeed correct and bail out if not.

commit bce1305c upstream. It appears that a ReportSize value of zero is legal, even if a bit non-sensical. Most of the HID code seems to handle that gracefully, except when computing the total size in bytes. When fed as input to memset, this leads to some funky outcomes. Detect the corner case and correctly compute the size. Cc: stable@vger.kernel.org Signed-off-by:

commit 25a097f5 upstream. `uref->usage_index` is not always being properly checked, causing hiddev_ioctl_usage() to go out of bounds under some cases. Fix it.

[ Upstream commit 6c4e79d9 ] The size of the buffers for storing context's and sessions can vary from arch to arch as PAGE_SIZE can be anything between 4 kB and 256 kB (the maximum for PPC64). Define a fixed buffer size set to 16 kB. This should be enough for most use with three handles (that is how many we allow at the moment). Parametrize the buffer size while doing this, so that it is easier to revisit this later on if required. Cc: stable@vger.kernel.org Reported-by:

[ Upstream commit d2ee3ff7 ] The usb_request->zero doesn't apply for isoc. Also, if we prepare a 0-length (ZLP) TRB for the OUT direction, we need to prepare an extra TRB to pad up to the MPS alignment. Use the same bounce buffer for the ZLP TRB and the extra pad TRB.

[ Upstream commit 5d187c04 ] The SG list may be set up with entry size more than the requested length. Check the usb_request->length and make sure that we don't setup the TRBs to send/receive more than requested. This case may occur when the SG entry is allocated up to a certain minimum size, but the request length is less than that. It can also occur when the request is reused for a different request length.

[ Upstream commit fb2fecba ] With my new locking code dbench is so much faster that I tripped over a transaction abort from ENOSPC. This turned out to be because btrfs_del_dir_entries_in_log was checking for ret == -ENOSPC, but this function sets err on error, and returns err. So instead of properly marking the inode as needing a full commit, we were returning -ENOSPC and aborting in __btrfs_unlink_inode. Fix this by checking the proper variable so that we return the correct thing in the case of ENOSPC. The ENOENT needs to be checked, because btrfs_lookup_dir_item_index() can return -ENOENT if the dir item isn't in the tree log (which would happen if we hadn't fsync'ed this guy). We actually handle that case in __btrfs_unlink_inode, so it's an expected error to get back.
