- fprobe: Fix to remove fprobe_hlist_node when module unloading When a fprobe target module is removed, the fprobe_hlist_node should be removed from the fprobe's hash table to prevent reusing accidentally if another module is loaded at the same address. - fprobe: Fix to lock module while registering fprobe The module containing the function to be probeed is locked using a reference counter until the fprobe registration is complete, which prevents use after free. - fprobe-events: Fix possible UAF on modules Basically as same as above, but in the fprobe-events layer we also need to get module reference counter when we find the tracepoint in the module. -----BEGIN PGP SIGNATURE----- iQFPBAABCgA5FiEEh7BulGwFlgAOi5DV2/sHvwUrPxsFAmf0kJ8bHG1hc2FtaS5o aXJhbWF0c3VAZ21haWwuY29tAAoJENv7B78FKz8b+bEIALiFuYBn2y26OJnfaRnW rgSC2JupswEVg7HwsN5kA/x1ypXl9SPfJGjbiHLUTq9+4KGOBTmY+k5/OpVO+Qkh 3nYKOkZxKRTglA7hRSTH0rxDV1eobps4nv/xkPjprugcjCGU54+4yb9Hq7Kyflpa o8p+VS/0VOJ9f3Iy9a9JRfu9qE7Qzz9USCj4N64WMgx/qczPe27twqFEaUpTf1VW Sw9twtKnqGs9hNE2QmhlzUBuq6gOZMXkjH6t1U4pMWBGB51JqZ5ZBhC4kL/5XEIZ bEau82El5qdieQC2B7c0RxldceKa4t4QUlJDalZGKpxvTXrCw9rFyv0dRe2cXnKm Yo0= =I+MO -----END PGP SIGNATURE----- Merge tag 'probes-fixes-v6.14' of git://git.kernel.org/pub/scm/linux/kernel/git/trace/linux-trace Pull probes fixes from Masami Hiramatsu: - fprobe: remove fprobe_hlist_node when module unloading When a fprobe target module is removed, the fprobe_hlist_node should be removed from the fprobe's hash table to prevent reusing accidentally if another module is loaded at the same address. - fprobe: lock module while registering fprobe The module containing the function to be probeed is locked using a reference counter until the fprobe registration is complete, which prevents use after free. - fprobe-events: fix possible UAF on modules Basically as same as above, but in the fprobe-events layer we also need to get module reference counter when we find the tracepoint in the module. * tag 'probes-fixes-v6.14' of git://git.kernel.org/pub/scm/linux/kernel/git/trace/linux-trace: tracing: fprobe: Cleanup fprobe hash when module unloading tracing: fprobe events: Fix possible UAF on modules tracing: fprobe: Fix to lock module while registering fprobe |
