[PATCH OLK-5.10] tracing: branch: Fix inverted check on stat tracer registration
by Tengda Wu 25 May '26

25 May '26

From: Breno Leitao <leitao(a)debian.org> mainline inclusion from mainline-v7.1-rc2 commit 3b75dd76e64a04771861bb5647951c264919e563 category: bugfix bugzilla: https://atomgit.com/openeuler/kernel/issues/9232 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?… -------------------------------- init_annotated_branch_stats() and all_annotated_branch_stats() check the return value of register_stat_tracer() with "if (!ret)", but register_stat_tracer() returns 0 on success and a negative errno on failure. The inverted check causes the warning to be printed on every successful registration, e.g.: Warning: could not register annotated branches stats while leaving real failures silent. The initcall also returned a hard-coded 1 instead of the actual error. Invert the check and propagate ret so that the warning fires on real errors and the initcall reports the correct status.

[PATCH OLK-6.6] pstore/ram: fix resource leak when ioremap() fails
by Luo Gengkun 25 May '26

25 May '26

From: Cole Leavitt <cole(a)unwrap.rs> mainline inclusion from mainline-v7.1-rc1 commit 2ddb69f686ef7a621645e97fc7329c50edf5d0e5 category: bugfix bugzilla: https://atomgit.com/src-openeuler/kernel/issues/15064 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… ---------------------------------------------------------------------- In persistent_ram_iomap(), ioremap() or ioremap_wc() may return NULL on failure. Currently, if this happens, the function returns NULL without releasing the memory region acquired by request_mem_region(). This leads to a resource leak where the memory region remains reserved but unusable. Additionally, the caller persistent_ram_buffer_map() handles NULL correctly by returning -ENOMEM, but without this check, a NULL return combined with request_mem_region() succeeding leaves resources in an inconsistent state. This is the ioremap() counterpart to commit 05363abc7625 ("pstore: ram_core: fix incorrect success return when vmap() fails") which fixed a similar issue in the vmap() path.

The premature netif_wake_queue() can re-enable TX while tx_urb is still in-flight, leading to a double usb_submit_urb() on the same URB: kaweth_start_xmit() { netif_stop_queue(); usb_submit_urb(kaweth->tx_urb); } kaweth_set_rx_mode() { netif_stop_queue(); netif_wake_queue(); // wakes TX queue before URB is done } kaweth_start_xmit() { netif_stop_queue(); usb_submit_urb(kaweth->tx_urb); // URB submitted while active } This triggers the WARN in usb_submit_urb(): "URB submitted while active" This is a similar class of bug fixed in rtl8150 by - commit 958baf5eaee3 ("net: usb: Remove disruptive netif_wake_queue in rtl8150_set_multicast"). Also kaweth_set_rx_mode() is already functionally broken, the real set_rx_mode action is performed by kaweth_async_set_rx_mode(), which in turn is not a no-op only at ndo_open() time.
