[ Upstream commit 3cd2c313 ] On the CP110 components which are present on the Armada 7K/8K SoC we need to explicitly enable the clock for the registers. However it is not needed for the AP8xx component, that's why this clock is optional. With this patch both clock have now a name, but in order to be backward compatible, the name of the first clock is not used. It allows to still use this clock with a device tree using the old binding. Reviewed-by:

[ Upstream commit ac68b1b3 ] As reported by Dan the parentheses is in the wrong place, and since unlikely() call returns either 0 or 1 it's never less than zero. The second issue is that signed integer overflows like "INT_MAX + 1" are undefined behavior. Since num_test_devs represents the number of devices, we want to stop prior to hitting the max, and not rely on the wrap arround at all. So just cap at num_test_devs + 1, prior to assigning a new device.

[ Upstream commit e21da1c9 ] A recent update to the ARM SMCCC ARCH_WORKAROUND_1 specification allows firmware to return a non zero, positive value to describe that although the mitigation is implemented at the higher exception level, the CPU on which the call is made is not affected. Let's relax the check on the return value from ARCH_WORKAROUND_1 so that we only error out if the returned value is negative.

[ Upstream commit bb7f8f19 ] resolved_dev returned might be NULL as ifindex is transient number. Ignoring NULL check of resolved_dev might crash the kernel. Therefore perform NULL check before accessing resolved_dev. Additionally rdma_resolve_ip_route() invokes addr_resolve() which performs check and address translation for loopback ifindex. Therefore, checking it again in rdma_resolve_ip_route() is not helpful. Therefore, the code is simplified to avoid IFF_LOOPBACK check.

[ Upstream commit 9de506a5 ] Rdma requires ILT Memory to be allocated for it's QPs. Each ILT entry points to a page used by several Rdma QPs. To avoid allocating all the memory in advance, the rdma implementation dynamically allocates memory as more QPs are added, however it does not dynamically free the memory. The memory should have been freed on rmmod qedr, but isn't. This patch adds the memory freeing on rmmod qedr (currently it will be freed with qed is removed). An outcome of this bug, is that if qedr is unloaded and loaded without unloaded qed, there will be no more RoCE traffic. The reason these are related, is that the logic of detecting the first QP ever opened is by asking whether ILT memory for RoCE has been allocated. In addition, this patch modifies freeing of the Task context to always use the PROTOCOLID_ROCE and not the protocol passed, this is because task context for iWARP and ROCE both use the ROCE protocol id, as opposed to the connection context.

[ Upstream commit 250c6c49 ] Fixing arbitrary kernel leak in case FBIOGETCMAP_SPARC in sbusfb_ioctl_helper(). 'index' is defined as an int in sbusfb_ioctl_helper(). We retrieve this from the user: if (get_user(index, &c->index) || __get_user(count, &c->count) || __get_user(ured, &c->red) || __get_user(ugreen, &c->green) || __get_user(ublue, &c->blue)) return -EFAULT; and then we use 'index' in the following way: red = cmap->red[index + i] >> 8; green = cmap->green[index + i] >> 8; blue = cmap->blue[index + i] >> 8; This is a classic information leak vulnerability. 'index' should be an unsigned int, given its usage above. This patch is straight-forward; it changes 'index' to unsigned int in two switch-cases: FBIOGETCMAP_SPARC && FBIOPUTCMAP_SPARC.

[ Upstream commit a1817792 ] The commit cited below added a gid_type field (RoCEv1 or RoCEv2) to GID properties. When adding GIDs, this gid_type field was copied over to the hardware gid table. However, when deleting GIDs, the gid_type field was not copied over to the hardware gid table. As a result, when running RoCEv2, all RoCEv2 gids in the hardware gid table were set to type RoCEv1 when any gid was deleted. This problem would persist until the next gid was added (which would again restore the gid_type field for all the gids in the hardware gid table). Fix this by copying over the gid_type field to the hardware gid table when deleting gids, so that the gid_type of all remaining gids is preserved when a gid is deleted.

[ Upstream commit 0077416a ] When using IPv4 addresses in RoCEv2, the GID format for the mapped IPv4 address should be: ::ffff:<4-byte IPv4 address>. In the cited commit, IPv4 mapped IPV6 addresses had the 3 upper dwords zeroed out by memset, which resulted in deleting the ffff field. However, since procedure ipv6_addr_v4mapped() already verifies that the gid has format ::ffff:<ipv4 address>, no change is needed for the gid, and the memset can simply be removed.

We don't force evsel ids allocation when we have single event, because it's not needed. However we need it when we are in pipe mode even for single event as a key for evsel update event.

[ Upstream commit bee9d41b ] The netvsc device should propagate filters to the SR-IOV VF device (if present). The flags also need to be propagated to the VF device as well. This only really matters on local Hyper-V since Azure does not support multiple addresses. Signed-off-by:

[ Upstream commit 74c12c63 ] As the kernel doc describes too the code is supposed to skip adding multicast TT entries if both the WANT_ALL_IPV4 and WANT_ALL_IPV6 flags are present. Unfortunately, the current code even skips adding multicast TT entries if only either the WANT_ALL_IPV4 or WANT_ALL_IPV6 is present. This could lead to IPv6 multicast packet loss if only an IGMP but not an MLD querier is present for instance or vice versa.

[ Upstream commit 93ac3deb ] According to SBSA spec v3.1 section 5.3: All registers are 32 bits in size and should be accessed using 32-bit reads and writes. If an access size other than 32 bits is used then the results are IMPLEMENTATION DEFINED. [...] The Generic Watchdog is little-endian The current code uses readq to read the watchdog compare register which does a 64-bit access. This fails on ThunderX2 which does not implement 64-bit access to this register. Fix this by using lo_hi_readq() that does two 32-bit reads. Signed-off-by:

[ Upstream commit 7bd3e7b7 ] Watchdog close is "expected" when any byte is 'V' not just the last one. Writing "V" to the device fails because the last byte is the end of string. $ echo V > /dev/watchdog f71808e_wdt: Unexpected close, not stopping watchdog! Signed-off-by:

[ Upstream commit 84eef2b2 ] Commit 0933a578 ("rds: tcp: use sock_create_lite() to create the accept socket") has a reference counting issue in TCP socket creation when accepting a new connection. The code uses sock_create_lite() to create a kernel socket. But it does not do __module_get() on the socket owner. When the connection is shutdown and sock_release() is called to free the socket, the owner's reference count is decremented and becomes incorrect. Note that this bug only shows up when the socket owner is configured as a kernel module. v2: Update comments Fixes: 0933a578 ("rds: tcp: use sock_create_lite() to create the accept socket") Signed-off-by:

[ Upstream commit 6508de03 ] In the scheduler config command, the meaning of tid == 0xf was intended to indicate the configuration is for management frames. However, tid == 0xf was also used for the multicast queue that was meant only for multicast data frames, which resulted with the FW not encrypting multicast data frames. As multicast frames do not have a QoS header, fix this by setting tid == 0, to indicate that this is a data queue and not management one. Signed-off-by:

[ Upstream commit 7c305de2 ] Multicast frames for NL80211_IFTYPE_AP and NL80211_IFTYPE_ADHOC were directed to the broadcast station, however, as the broadcast station did not have keys configured, these frames were sent unencrypted. Fix this by using the multicast station which is the station for which encryption keys are configured. Signed-off-by:

[ Upstream commit e4f13ad0 ] When the GTK is installed, we install it to HW with the station ID of the AP. Mac80211 will try to remove it only after the AP sta is removed, which will result in a failure to remove key since we do not have any station for it. This is a valid situation, but a previous commit removed the early return and added a return with error value, which resulted in an error message that is confusing to users. Remove the error return value. Fixes: 85aeb58c ("iwlwifi: mvm: Enable security on new TX API") Signed-off-by:

[ Upstream commit 8745f12a ] Trying to collect firmware debug data while firmware is not loaded causes various errors (e.g. failing NIC access). This causes even a bigger issue if at that time the HW radio is off. In that case, when later turning the radio on, the Driver fails to read the HW (registers contain garbage values). (It may be that the CSR_GP_CNTRL_REG_FLAG_RFKILL_WAKE_L1A_EN bit is cleared on faulty NIC access - since the same behavior was seen in HW RFKILL toggling before setting that bit.) Signed-off-by:
