[ Upstream commit 86723c86 ] .ndo_xdp_xmit() assumes it is called under RCU. For example virtio_net uses RCU to detect it has setup the resources for tx. The assumption accidentally broke when introducing bulk queue in devmap. Fixes: 5d053f9d ("bpf: devmap prepare xdp frames for bulking") Reported-by:

[ Upstream commit d4dd153d ] dev_map_free() waits for flush_needed bitmap to be empty in order to ensure all flush operations have completed before freeing its entries. However the corresponding clear_bit() was called before using the entries, so the entries could be used after free. All access to the entries needs to be done before clearing the bit. It seems commit a5e2da6e ("bpf: netdev is never null in __dev_map_flush") accidentally changed the clear_bit() and memory access order. Note that the problem happens only in __dev_map_flush(), not in dev_map_flush_old(). dev_map_flush_old() is called only after nulling out the corresponding netdev_map entry, so dev_map_free() never frees the entry thus no such race happens there.

[ Upstream commit 1a473d60 ] The bits of Rx MCS Map in VHT capability were enumerated with index transform - index i -> (i + 1) bit => nss i. BUG! while it should be - index i -> (i + 1) bit => (i + 1) nss.

[ Upstream commit 56357234 ] In multiple SSID cases, it takes time to prepare every AP interface to be ready in initializing phase. If a sta already knows everything it needs to join one of the APs and sends authentication to the AP which is not fully prepared at this point of time, AP's channel context could be NULL. As a result, warning message occurs. Even worse, if the AP is under attack via tools such as MDK3 and massive authentication requests are received in a very short time, console will be hung due to kernel warning messages. WARN_ON_ONCE() could be a better way for indicating warning messages without duplicate messages to flood the console. Johannes: We still need to address the underlying problem, but we don't really have a good handle on it yet. Suppress the worst side-effects for now. Signed-off-by:

[ Upstream commit ce9a53eb ] There are several scenarios that keyboard can NOT wake up system from suspend, e.g., if a keyboard is depressed between system device suspend phase and device noirq suspend phase, the keyboard ISR will be called and both keyboard depress and release interrupts will be disabled, then keyboard will no longer be able to wake up system. Another scenario would be, if a keyboard is kept depressed, and then system goes into suspend, the expected behavior would be when keyboard is released, system will be waked up, but current implementation can NOT achieve that, because both depress and release interrupts are disabled in ISR, and the event check is still in progress. To fix these issues, need to make sure keyboard's depress or release interrupt is enabled after noirq device suspend phase, this patch moves the suspend/resume callback to noirq suspend/resume phase, and enable the corresponding interrupt according to current keyboard status.

This has the added benefit of providing a unique identifier. On 64-bit machines the first 32 bits are zeroed. The kernel will print ``(ptrval)`` until it gathers enough entropy."

[ Upstream commit 3e82f2f3 ] During frame reception while the MCAN is in Error Passive state and the Receive Error Counter has thevalue MCAN_ECR.REC = 127, it may happen that MCAN_IR.MRAF is set although there was no Message RAM access failure. If MCAN_IR.MRAF is enabled, an interrupt to the Host CPU is generated. Work around: The Message RAM Access Failure interrupt routine needs to check whether MCAN_ECR.RP = '1' and MCAN_ECR.REC = '127'. In this case, reset MCAN_IR.MRAF. No further action is required. This affects versions older than 3.2.0 Errata explained on Sama5d2 SoC which includes this hardware block: http://ww1.microchip.com/downloads/en/DeviceDoc/SAMA5D2-Family-Silicon-Errata-and-Data-Sheet-Clarification-DS80000803B.pdf chapter 6.2 Reproducibility: If 2 devices with m_can are connected back to back, configuring different bitrate on them will lead to interrupt storm on the receiving side, with error "Message RAM access failure occurred". Another way is to have a bad hardware connection. Bad wire connection can lead to this issue as well. This patch fixes the issue according to provided workaround. Signed-off-by:

[ Upstream commit 8a3dca63 ] When fixing the skb leak introduced by the conversion to rbtree, I forgot about the special case of duplicate fragments. The condition under the 'insert_error' label isn't effective anymore as nf_ct_frg6_gather() doesn't override the returned value anymore. So duplicate fragments now get NF_DROP verdict. To accept duplicate fragments again, handle them specially as soon as inet_frag_queue_insert() reports them. Return -EINPROGRESS which will translate to NF_STOLEN verdict, like any accepted fragment. However, such packets don't carry any new information and aren't queued, so we just drop them immediately.

[ Upstream commit 1884c066 ] In commit 9a5ab8bf ("tools: bpftool: turn err() and info() macros into functions") one case of error reporting was special cased, so it could report a lookup error for a specific key when dumping the map element. What the code forgot to do is to wrap the key and value keys into a JSON object, so an example output of pretty JSON dump of a sockhash map (which does not support looking up its values) is: [ "key": ["0x0a","0x41","0x00","0x02","0x1f","0x78","0x00","0x00" ], "value": { "error": "Operation not supported" }, "key": ["0x0a","0x41","0x00","0x02","0x1f","0x78","0x00","0x01" ], "value": { "error": "Operation not supported" } ] Note the key-value pairs inside the toplevel array. They should be wrapped inside a JSON object, otherwise it is an invalid JSON. This commit fixes this, so the output now is: [{ "key": ["0x0a","0x41","0x00","0x02","0x1f","0x78","0x00","0x00" ], "value": { "error": "Operation not supported" } },{ "key": ["0x0a","0x41","0x00","0x02","0x1f","0x78","0x00","0x01" ], "value": { "error": "Operation not supported" } } ] Fixes: 9a5ab8bf ("tools: bpftool: turn err() and info() macros into functions") Cc: Quentin Monnet <quentin.monnet@netronome.com> Signed-off-by:

[ Upstream commit a0d56cb9 ] With commit 997dd964 ("net: IP6 defrag: use rbtrees in nf_conntrack_reasm.c"), nf_ct_frag6_reasm() is now called from nf_ct_frag6_queue(). With this change, nf_ct_frag6_queue() can fail after the skb has been added to the fragment queue and nf_ct_frag6_gather() was adapted to handle this case. But nf_ct_frag6_queue() can still fail before the fragment has been queued. nf_ct_frag6_gather() can't handle this case anymore, because it has no way to know if nf_ct_frag6_queue() queued the fragment before failing. If it didn't, the skb is lost as the error code is overwritten with -EINPROGRESS. Fix this by setting -EINPROGRESS directly in nf_ct_frag6_queue(), so that nf_ct_frag6_gather() can propagate the error as is.

[ Upstream commit 69ae4f6a ] A few places in mwifiex_uap_parse_tail_ies() perform memcpy() unconditionally, which may lead to either buffer overflow or read over boundary. This patch addresses the issues by checking the read size and the destination size at each place more properly. Along with the fixes, the patch cleans up the code slightly by introducing a temporary variable for the token size, and unifies the error path with the standard goto statement. Reported-by:

[ Upstream commit a8627176 ] In the error handling code of iwl_req_fw_callback(), iwl_dealloc_ucode() is called to free data. In iwl_drv_stop(), iwl_dealloc_ucode() is called again, which can cause double-free problems. To fix this bug, the call to iwl_dealloc_ucode() in iwl_req_fw_callback() is deleted. This bug is found by a runtime fuzzing tool named FIZZER written by us. Signed-off-by:
