This is a race condition that was initially fixed in 2009, -but inadvertantly re-introduced in the latest release when the code -was rewritten. - -Background: - -When finalising the filesystem, the main control thread needs to ensure -all the in-flight fragments have been queued to the writer thread before -asking the writer thread to finish, and then writing the metadata. - -It does this by waiting on the fragments_outstanding counter. Once this -counter reaches 0, it synchronises with the writer thread, waiting until -the writer thread reports no outstanding data to be written. - -However, the main thread can race with the fragment deflator thread(s) -because the fragment deflator thread(s) decrement the fragments_outstanding -counter and release the mutex before queueing the compressed fragment -to the writer thread, i.e. the offending code is: - - fragments_outstanding --; - pthread_mutex_unlock(&fragment_mutex); - queue_put(to_writer, write_buffer); - -In extremely rare circumstances, the main thread may see the -fragments_outstanding counter is zero before the fragment -deflator sends the fragment buffer to the writer thread, and synchronise -with the writer thread, and finalise before the fragment has been written. - -The fix is to ensure the fragment is queued to the writer thread -before releasing the mutex. - -Signed-off-by: Phillip Lougher <phillip@squashfs.org.uk> ---- - squashfs-tools/mksquashfs.c | 2 +- - 1 file changed, 1 insertion(+), 1 deletion(-) - -diff --git a/squashfs-tools/mksquashfs.c b/squashfs-tools/mksquashfs.c -index 87b7d86..f1fcff1 100644 ---- a/squashfs-tools/mksquashfs.c -+++ b/squashfs-tools/mksquashfs.c -@@ -2419,8 +2419,8 @@ void *frag_deflator(void *arg) - write_buffer->block = bytes; - bytes += compressed_size; - fragments_outstanding --; -- pthread_mutex_unlock(&fragment_mutex); - queue_put(to_writer, write_buffer); -+ pthread_mutex_unlock(&fragment_mutex); - TRACE("Writing fragment %lld, uncompressed size %d, " - "compressed size %d\n", file_buffer->block, - file_buffer->size, compressed_size); --- -2.10.2 - diff --git a/user/squashfs-tools/APKBUILD b/user/squashfs-tools/APKBUILD index 227faf11d..c25eb0a83 100644 --- a/user/squashfs-tools/APKBUILD +++ b/user/squashfs-tools/APKBUILD @@ -1,35 +1,32 @@ # Maintainer: A.
