rxrpc, afs: Fix missing error pointer check after rxrpc_kernel_lookup_peer()

2026-03-07T01:49:52+00:00

rxrpc_kernel_lookup_peer() can also return error pointers in addition to NULL, so just checking for NULL is not sufficient. Fix this by: (1) Changing rxrpc_kernel_lookup_peer() to return -ENOMEM rather than NULL on allocation failure. (2) Making the callers in afs use IS_ERR() and PTR_ERR() to pass on the error code returned.

Convert 'alloc_flex' family to use the new default GFP_KERNEL argument

2026-02-22T01:09:51+00:00

This is the exact same thing as the 'alloc_obj()' version, only much smaller because there are a lot fewer users of the *alloc_flex() interface. As with alloc_obj() version, this was done entirely with mindless brute force, using the same script, except using 'flex' in the pattern rather than 'objs*'. Signed-off-by: Linus Torvalds

treewide: Replace kmalloc with kmalloc_obj for non-scalar types

2026-02-21T09:02:28+00:00

This is the result of running the Coccinelle script from scripts/coccinelle/api/kmalloc_objs.cocci. The script is designed to avoid scalar types (which need careful case-by-case checking), and instead replace kmalloc-family calls that allocate struct or union object instances: Single allocations: kmalloc(sizeof(TYPE), ...) are replaced with: kmalloc_obj(TYPE, ...) Array allocations: kmalloc_array(COUNT, sizeof(TYPE), ...) are replaced with: kmalloc_objs(TYPE, COUNT, ...) Flex array allocations: kmalloc(struct_size(PTR, FAM, COUNT), ...) are replaced with: kmalloc_flex(*PTR, FAM, COUNT, ...) (where TYPE may also be *VAR) The resulting allocations no longer return "void *", instead returning "TYPE *". Signed-off-by: Kees Cook

afs: Use the per-peer app data provided by rxrpc

2025-03-10T09:47:15+00:00

Make use of the per-peer application data that rxrpc now allows the application to store on the rxrpc_peer struct to hold a back pointer to the afs_server record that peer represents an endpoint for. Then, when a call comes in to the AFS cache manager, this can be used to map it to the correct server record rather than having to use a UUID-to-server mapping table and having to do an additional lookup.

afs: Fold the afs_addr_cursor struct in

Fold the afs_addr_cursor struct into the afs_operation struct and the afs_vl_cursor struct and fold its operations into their callers also. Signed-off-by: David Howells cc: Marc Dionne cc: linux-afs@lists.infradead.org

afs: Use peer + service_id as call address

2023-12-24T15:22:55+00:00

Use the rxrpc_peer plus the service ID as the call address instead of passing in a sockaddr_srx down to rxrpc. The peer record is obtained by using rxrpc_kernel_get_peer(). This avoids the need to repeatedly look up the peer and allows rxrpc to hold on to resources for it. Signed-off-by: David Howells cc: Marc Dionne cc: linux-afs@lists.infradead.org

afs: Simplify error handling

2023-12-24T15:22:53+00:00

Simplify error handling a bit by moving it from the afs_addr_cursor struct to the afs_operation and afs_vl_cursor structs and using the error prioritisation function for accumulating errors from multiple sources (AFS tries to rotate between multiple fileservers, some of which may be inaccessible or in some state of offlinedness).
