If user passed an interface option longer than 15 characters, then device.ifr_name and hwtstamp.ifr_name became non-null-terminated strings. The compiler warned about this: timestamping.c:353:2: warning: ‘strncpy’ specified bound 16 equals \ destination size [-Wstringop-truncation] 353 | strncpy(device.ifr_name, interface, sizeof(device.ifr_name)); Fixes: cb9eff09 ("net: new user space API for time stamping of incoming and outgoing packets") Signed-off-by:

David Howells says: ==================== rxrpc: Fix hang due to missing notification Here's a fix for AF_RXRPC. Occasionally calls hang because there are circumstances in which rxrpc generate a notification when a call is completed - primarily because initial packet transmission failed and the call was killed off and an error returned. But the AFS filesystem driver doesn't check this under all circumstances, expecting failure to be delivered by asynchronous notification. There are two patches: the first moves the problematic bits out-of-line and the second contains the fix. ==================== Signed-off-by:

In MPTCPOPT_RM_ADDR option parsing, the pointer "ptr" pointed to the "Subtype" octet, the pointer "ptr+1" pointed to the "Address ID" octet: +-------+-------+---------------+ |Subtype|(resvd)| Address ID | +-------+-------+---------------+ | | ptr ptr+1 We should set mp_opt->rm_id to the value of "ptr+1", not "ptr". This patch will fix this bug. Fixes: 3df523ab ("mptcp: Add ADD_ADDR handling") Signed-off-by:

Use vm_insert_pages() for tcp receive zerocopy. Spin lock cycles (as reported by perf) drop from a couple of percentage points to a fraction of a percent. This results in a roughly 6% increase in efficiency, measured roughly as zerocopy receive count divided by CPU utilization. The intention of this patchset is to reduce atomic ops for tcp zerocopy receives, which normally hits the same spinlock multiple times consecutively.

This selftest tests for cases where sendfile's 'count' parameter is provided with a size greater than the intended file size. Motivation: When sendfile is provided with 'count' parameter value that is greater than the size of the file, kTLS example fails to send the file correctly. Last chunk of the file is not sent, and the data integrity is compromised. The reason is that the last chunk has MSG_MORE flag set because of which it gets added to pending records, but is not pushed. Note that if user space were to send SSL_shutdown control message, pending records would get flushed and the issue would not happen. So a shutdown control message following sendfile can mask the issue. Signed-off-by:

While trying to use the lantiq_gswip driver on one of my boards I made a mistake when specifying the phy-mode (because the out-of-tree driver wants phy-mode "gmii" or "mii" for the internal PHYs). In this case the following error is printed multiple times: Unsupported interface: 3 While it gives at least a hint at what may be wrong it is not very user friendly. Print the human readable phy-mode and also which port is configured incorrectly (this hardware supports ports 0..6) to improve the cases where someone made a mistake.

The driver registers three different types of thermal zones: For the ASIC itself, for port modules and for gearboxes. Currently, all three types use the same get_trend() callback which does not work correctly for the ASIC thermal zone. The callback assumes that the device data is of type 'struct mlxsw_thermal_module', whereas for the ASIC thermal zone 'struct mlxsw_thermal' is passed as device data. Fix this by using one get_trend() callback for the ASIC thermal zone and another for the other two types. Fixes: 6f73862f ("mlxsw: core: Add the hottest thermal zone detection") Signed-off-by:

Commit 6cc7c266 ("ima: Call ima_calc_boot_aggregate() in ima_eventdigest_init()") added a call to ima_calc_boot_aggregate() so that the digest can be recalculated for the boot_aggregate measurement entry if the 'd' template field has been requested. For the 'd' field, only SHA1 and MD5 digests are accepted. Given that ima_eventdigest_init() does not have the __init annotation, all functions called should not have it.

Fix two issues with introspecting the task mode. 1. If a task is attached to a unconfined profile that is not the ns->unconfined profile then. Mode the mode is always reported as - $ ps -Z LABEL PID TTY TIME CMD unconfined 1287 pts/0 00:00:01 bash test (-) 1892 pts/0 00:00:00 ps instead of the correct value of (unconfined) as shown below $ ps -Z LABEL PID TTY TIME CMD unconfined 2483 pts/0 00:00:01 bash test (unconfined) 3591 pts/0 00:00:00 ps 2. if a task is confined by a stack of profiles that are unconfined the output of label mode is again the incorrect value of (-) like above, instead of (unconfined). This is because the visibile profile count increment is skipped by the special casing of unconfined. Fixes: f1bd9041 ("apparmor: add the base fns() for domain labels") Signed-off-by:

Currently apparmor_sk_clone_security() does not check for existing label/peer in the 'new' struct sock; it just overwrites it, if any (with another reference to the label of the source sock.) static void apparmor_sk_clone_security(const struct sock *sk, struct sock *newsk) { struct aa_sk_ctx *ctx = SK_CTX(sk); struct aa_sk_ctx *new = SK_CTX(newsk); new->label = aa_get_label(ctx->label); new->peer = aa_get_label(ctx->peer); } This might leak label references, which might overflow under load. Thus, check for and put labels, to prevent such errors. Note this is similarly done on: static int apparmor_socket_post_create(struct socket *sock, ...) ... if (sock->sk) { struct aa_sk_ctx *ctx = SK_CTX(sock->sk); aa_put_label(ctx->label); ctx->label = aa_get_label(label); } ... Context: ------- The label reference count leak is observed if apparmor_sock_graft() is called previously: this sets the 'ctx->label' field by getting a reference to the current label (later overwritten, without put.) static void apparmor_sock_graft(struct sock *sk, ...) { struct aa_sk_ctx *ctx = SK_CTX(sk); if (!ctx->label) ctx->label = aa_get_current_label(); } And that is the case on crypto/af_alg.c:af_alg_accept(): int af_alg_accept(struct sock *sk, struct socket *newsock, ...) ... struct sock *sk2; ... sk2 = sk_alloc(...); ... security_sock_graft(sk2, newsock); security_sk_clone(sk, sk2); ... Apparently both calls are done on their own right, especially for other LSMs, being introduced in 2010/2014, before apparmor socket mediation in 2017 (see commits [1,2,3,4]). So, it looks OK there!

When the PHY's strap register is read to determine if lane swapping is needed the phy_read_mmd returns the value back into the ret variable. If the call to read the strap fails the failed value is returned. If the call to read the strap is successful then ret is possibly set to a non-zero positive number. Without reseting the ret value to 0 this will cause the parse DT function to return a failure. Fixes: c4566aec ("net: phy: dp83869: Update port-mirroring to read straps") Signed-off-by:

This patch replaces some unnecessary uses of rcu_dereference_raw in the rhashtable code with rcu_dereference_protected. The top-level nested table entry is only marked as RCU because it shares the same type as the tree entries underneath it. So it doesn't need any RCU protection. We also don't need RCU protection when we're freeing a nested RCU table because by this stage we've long passed a memory barrier when anyone could change the nested table. Signed-off-by:
