[PATCH net 0/4] mptcp: various rare sending issues

by Matthieu Baerts (NGI0)

Here are various fixes from Paolo, addressing very occasional issues on the sending side: - Patch 1: drop an optimisation that could lead to timeout in case of race conditions. A fix for up to v5.11. - Patch 2: fix stream corruption under very specific conditions. A fix for up to v5.13. - Patch 3: restore MPTCP-level zero window probe after a recent fix. A fix for up to v5.16. - Patch 4: new MIB counter to track MPTCP-level zero windows probe to help catching issues similar to the one fixed by the previous patch.

[PATCH] drm/ast: Clear preserved bits from register output value

by Thomas Zimmermann

Preserve the I/O register bits in __ast_write8_i_masked() as specified by preserve_mask. Accidentally OR-ing the output value into these will overwrite the register's previous settings. Fixes display output on the AST2300, where the screen can go blank at boot. The driver's original commit 312fec1405dd ("drm: Initial KMS driver for AST (ASpeed Technologies) 2000 series (v2)") already added the broken code. Commit 6f719373b943 ("drm/ast: Blank with VGACR17 sync enable, always clear VGACRB6 sync off") triggered the bug.

[PATCH] dma: qcom: gpi: Fix memory leak in gpi_peripheral_config()

by Miaoqian Lin

Fix a memory leak in gpi_peripheral_config() where the original memory pointed to by gchan->config could be lost if krealloc() fails. The issue occurs when: 1. gchan->config points to previously allocated memory 2. krealloc() fails and returns NULL 3. The function directly assigns NULL to gchan->config, losing the reference to the original memory 4. The original memory becomes unreachable and cannot be freed Fix this by using a temporary variable to hold the krealloc() result and only updating gchan->config when the allocation succeeds. Found via static analysis and code review.

[PATCH v1] mm/mm_init: Fix hash table order logging in alloc_large_system_hash()

by Isaac J. Manjarres

When emitting the order of the allocation for a hash table, alloc_large_system_hash() unconditionally subtracts PAGE_SHIFT from log base 2 of the allocation size. This is not correct if the allocation size is smaller than a page, and yields a negative value for the order as seen below: TCP established hash table entries: 32 (order: -4, 256 bytes, linear) TCP bind hash table entries: 32 (order: -2, 1024 bytes, linear) Use get_order() to compute the order when emitting the hash table information to correctly handle cases where the allocation size is smaller than a page: TCP established hash table entries: 32 (order: 0, 256 bytes, linear) TCP bind hash table entries: 32 (order: 0, 1024 bytes, linear) Fixes: 1da177e4c3f4 ("Linux-2.6.12-rc2") Cc: stable(a)vger.kernel.org # v5.4+ Signed-off-by: Isaac J.

[PATCH] drm/sun4i: Fix device node reference leak in sun4i_tcon_of_get_id_from_port

by Miaoqian Lin

Fix a device node reference leak where the remote endpoint node obtained by of_graph_get_remote_endpoint() was not being properly released. Add of_node_put() calls after of_property_read_u32() to fix this.
