The problem is that an # asynchronous call that holds a resource pointed to by call->reply[0] will # find the pointer cleared in the call destructor, thereby preventing the # resource from being cleaned up. # # In the case of the server record leak, the afs_fs_get_capabilities() # function in devel code sets up a call with reply[0] pointing at the server # record that should be altered when the result is obtained, but this was # being cleared before the destructor was called, so the put in the # destructor does nothing and the record is leaked. # # Commit f014ffb025c1 removed the additional ref obtained by # afs_install_server(), but the removal of this ref is actually used by the # garbage collector to mark a server record as being defunct after the record # has expired through lack of use. # # The offending clearance of call->reply[0] upon completion in # afs_process_async_call() has been there from the origin of the code, but # none of the asynchronous calls actually use that pointer currently, so it # should be safe to remove (note that synchronous calls don't involve this # function). # # Fix this by the following means: # # (1) Revert commit f014ffb025c1. # # (2) Remove the clearance of reply[0] from afs_process_async_call(). # # Without this, afs_manage_servers() will suffer an assertion failure if it # sees a server record that didn't get used because the usage count is not 1. # # Fixes: f014ffb025c1 ("afs: Fix afs_server struct leak") # Fixes: 08e0e7c82eea ("[AF_RXRPC]: Make the in-kernel AFS filesystem use AF_RXRPC.") # Signed-off-by: David Howells <dhowells@redhat.com> # Cc: stable <stable@vger.kernel.org> # Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org> # < /opt/cross/kisskb/korg/gcc-8.1.0-nolibc/mips-linux/bin/mips-linux-gcc --version # < git log --format=%s --max-count=1 f0a7d1883d9f78ae7bf15fc258bf9a2b20f35b76 # < make -s -j 120 ARCH=mips O=/kisskb/build/linus_mips-allmodconfig_mips-gcc8 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-8.1.0-nolibc/mips-linux/bin/mips-linux- allmodconfig # Added to kconfig CONFIG_BUILD_DOCSRC=n # Added to kconfig CONFIG_MODULE_SIG=n # Added to kconfig CONFIG_SAMPLES=n # Added to kconfig CONFIG_MIPS_CPS_NS16550_BASE=0x1b0003f8 # Added to kconfig CONFIG_MIPS_CPS_NS16550_SHIFT=0 # yes \n \| make -s -j 120 ARCH=mips O=/kisskb/build/linus_mips-allmodconfig_mips-gcc8 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-8.1.0-nolibc/mips-linux/bin/mips-linux- oldconfig yes: standard output: Broken pipe # make -s -j 120 ARCH=mips O=/kisskb/build/linus_mips-allmodconfig_mips-gcc8 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-8.1.0-nolibc/mips-linux/bin/mips-linux- /kisskb/src/drivers/input/joystick/analog.c:172:2: warning: #warning Precise timer not defined for this architecture.
