2021-07-14fs: add vfs_parse_fs_param_source() helperChristian Brauner3-27/+43
Add a simple helper that filesystems can use in their parameter parser to parse the "source" parameter. A few places open-coded this function and that already caused a bug in the cgroup v1 parser that we fixed. Let's make it harder to get this wrong by introducing a helper which performs all necessary checks.

2021-07-14cgroup: verify that source is a stringChristian Brauner1-0/+2
The following sequence can be used to trigger a UAF: int fscontext_fd = fsopen("cgroup"); int fd_null = open("/dev/null, O_RDONLY); int fsconfig(fscontext_fd, FSCONFIG_SET_FD, "source", fd_null); close_range(3, ~0U, 0); The cgroup v1 specific fs parser expects a string for the "source" parameter. However, it is perfectly legitimate to e.g. specify a file descriptor for the "source" parameter. The fs parser doesn't know what a filesystem allows there. So it's a bug to assume that "source" is always of type fs_value_is_string when it can reasonably also be fs_value_is_file. This assumption in the cgroup code causes a UAF because struct fs_parameter uses a union for the actual value. Access to that union is guarded by the param->type member. Since the cgroup paramter parser didn't check param->type but unconditionally moved param->string into fc->source a close on the fscontext_fd would trigger a UAF during put_fs_context() which frees fc->source thereby freeing the file stashed in param->file causing a UAF during a close of the fd_null. Fix this by verifying that param->type is actually a string and report an error if not. In follow up patches I'll add a new generic helper that can be used here and by other filesystems instead of this error-prone copy-pasta fix. But fixing it in here first makes backporting a it to stable a lot easier.

2021-07-13Merge branch 'sfc-tx-queues'David S. Miller1-8/+14
Íñigo Huguet says: ==================== sfc: Fix lack of XDP TX queues A change introduced in commit e26ca4b53582 ("sfc: reduce the number of requested xdp ev queues") created a bug in XDP_TX and XDP_REDIRECT because it unintentionally reduced the number of XDP TX queues, letting not enough queues to have one per CPU, which leaded to errors if XDP TX/REDIRECT was done from a high numbered CPU. This patchs make the following changes: - Fix the bug mentioned above - Revert commit 99ba0ea616aa ("sfc: adjust efx->xdp_tx_queue_count with the real number of initialized queues") which intended to fix a related problem, created by mentioned bug, but it's no longer necessary - Add a new error log message if there are not enough resources to make XDP_TX/REDIRECT work V1 -> V2: keep the calculation of how many tx queues can handle a single event queue, but apply the "max. tx queues per channel" upper limit. V2 -> V3: WARN_ON if the number of initialized XDP TXQs differs from the expected. ==================== Signed-off-by: David S. Miller <davem@davemloft.net>

If it's not possible to allocate enough channels for XDP, XDP_TX and XDP_REDIRECT don't work. However, only a message saying that not enough channels were available was shown, but not saying what are the consequences in that case. The user didn't know if he/she can use XDP or not, if the performance is reduced, or what. Signed-off-by: Íñigo Huguet <ihuguet@redhat.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2021-07-13sfc: ensure correct number of XDP queuesÍñigo Huguet1-7/+8
Commit 99ba0ea616aa ("sfc: adjust efx->xdp_tx_queue_count with the real number of initialized queues") intended to fix a problem caused by a round up when calculating the number of XDP channels and queues. However, this was not the real problem. The real problem was that the number of XDP TX queues had been reduced to half in commit e26ca4b53582 ("sfc: reduce the number of requested xdp ev queues"), but the variable xdp_tx_queue_count had remained the same. Once the correct number of XDP TX queues is created again in the previous patch of this series, this also can be reverted since the error doesn't actually exist. Only in the case that there is a bug in the code we can have different values in xdp_queue_number and efx->xdp_tx_queue_count. Because of this, and per Edward Cree's suggestion, I add instead a WARN_ON to catch if it happens again in the future. Note that the number of allocated queues can be higher than the number of used ones due to the round up, as explained in the existing comment in the code. That's why we also have to stop increasing xdp_queue_number beyond efx->xdp_tx_queue_count. Signed-off-by: Íñigo Huguet <ihuguet@redhat.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2021-07-13sfc: fix lack of XDP TX queues - error XDP TX failed (-22)Íñigo Huguet1-1/+2
Fixes: e26ca4b53582 sfc: reduce the number of requested xdp ev queues The buggy commit intended to allocate less channels for XDP in order to be more unlikely to reach the limit of 32 channels of the driver. The idea was to use each IRQ/eventqeue for more XDP TX queues than before, calculating which is the maximum number of TX queues that one event queue can handle. For example, in EF10 each event queue could handle up to 8 queues, better than the 4 they were handling before the change. This way, it would have to allocate half of channels than before for XDP TX. The problem is that the TX queues are also contained inside the channel structs, and there are only 4 queues per channel. Reducing the number of channels means also reducing the number of queues, resulting in not having the desired number of 1 queue per CPU. This leads to getting errors on XDP_TX and XDP_REDIRECT if they're executed from a high numbered CPU, because there only exist queues for the low half of CPUs, actually. If XDP_TX/REDIRECT is executed in a low numbered CPU, the error doesn't happen. This is the error in the logs (repeated many times, even rate limited): sfc 0000:5e:00.0 ens3f0np0: XDP TX failed (-22) This errors happens in function efx_xdp_tx_buffers, where it expects to have a dedicated XDP TX queue per CPU. Reverting the change makes again more likely to reach the limit of 32 channels in machines with many CPUs. If this happen, no XDP_TX/REDIRECT will be possible at all, and we will have this log error messages: At interface probe: sfc 0000:5e:00.0: Insufficient resources for 12 XDP event queues (24 other channels, max 32) At every subsequent XDP_TX/REDIRECT failure, rate limited: sfc 0000:5e:00.0 ens3f0np0: XDP TX failed (-22) However, without reverting the change, it makes the user to think that everything is OK at probe time, but later it fails in an unpredictable way, depending on the CPU that handles the packet. It is better to restore the predictable behaviour. If the user sees the error message at probe time, he/she can try to configure the best way it fits his/her needs. At least, he/she will have 2 options: - Accept that XDP_TX/REDIRECT is not available (he/she may not need it) - Load sfc module with modparam 'rss_cpus' with a lower number, thus creating less normal RX queues/channels, letting more free resources for XDP, with some performance penalty. Anyway, let the calculation of maximum TX queues that can be handled by a single event queue, and use it only if it's less than the number of TX queues per channel. This doesn't happen in practice, but could happen if some constant values are tweaked in the future, such us EFX_MAX_TXQ_PER_CHANNEL, EFX_MAX_EVQ_SIZE or EFX_MAX_DMAQ_SIZE.

2021-07-13net: dsa: sja1105: fix address learning getting disabled on the CPU portVladimir Oltean1-8/+6
In May 2019 when commit 640f763f98c2 ("net: dsa: sja1105: Add support for Spanning Tree Protocol") was introduced, the comment that "STP does not get called for the CPU port" was true. This changed after commit 0394a63acfe2 ("net: dsa: enable and disable all ports") in August 2019 and went largely unnoticed, because the sja1105_bridge_stp_state_set() method did nothing different compared to the static setup done by sja1105_init_mac_settings(). With the ability to turn address learning off introduced by the blamed commit, there is a new priv->learn_ena port mask in the driver. When sja1105_bridge_stp_state_set() gets called and we are in BR_STATE_LEARNING or later, address learning is enabled or not depending on priv->learn_ena & BIT(port). So what happens is that priv->learn_ena is not being set from anywhere for the CPU port, and the static configuration done by sja1105_init_mac_settings() is being overwritten. To solve this, acknowledge that the static configuration of STP state is no longer necessary because the STP state is being set by the DSA core now, but what is necessary is to set priv->learn_ena for the CPU port.

2021-07-11mm/rmap: fix old bug: munlocking THP missed other mlocksHugh Dickins1-5/+8
The kernel recovers in due course from missing Mlocked pages: but there was no point in calling page_mlock() (formerly known as try_to_munlock()) on a THP, because nothing got done even when it was found to be mapped in another VM_LOCKED vma. It's true that we need to be careful: Mlocked accounting of pte-mapped THPs is too difficult (so consistently avoided); but Mlocked accounting of only-pmd-mapped THPs is supposed to work, even when multiple mappings are mlocked and munlocked or munmapped. Refine the tests. There is already a VM_BUG_ON_PAGE(PageDoubleMap) in page_mlock(), so page_mlock_one() does not even have to worry about that complication.

2021-07-11mm/rmap: fix comments left over from recent changesHugh Dickins2-7/+2
Parallel developments in mm/rmap.c have left behind some out-of-date comments: try_to_migrate_one() also accepts TTU_SYNC (already commented in try_to_migrate() itself), and try_to_migrate() returns nothing at all. TTU_SPLIT_FREEZE has just been deleted, so reword the comment about it in mm/huge_memory.c; and TTU_IGNORE_ACCESS was removed in 5.11, so delete the "recently referenced" comment from try_to_unmap_one() (once upon a time the comment was near the removed codeblock, but they drifted apart).

Nikolay Aleksandrov says: ==================== net: bridge: multicast: fix automatic router port marking races While working on per-vlan multicast snooping I found two race conditions when multicast snooping is enabled. They're identical and happen when the router port list is modified without the multicast lock. One requires a PIM hello message to be received on a port and the other an MRD advertisement. To fix them we just need to take the multicast_lock when adding the ports to the router port list (marking them as router ports). Tested on an affected setup by generating the required packets while modifying the port list in parallel. ==================== Signed-off-by: David S. Miller <davem@davemloft.net>

When an MRD advertisement is received on a bridge port with multicast snooping enabled, we mark it as a router port automatically, that includes adding that port to the router port list. The multicast lock protects that list, but it is not acquired in the MRD advertisement case leading to a race condition, we need to take it to fix the race.
