Fix libsquashfs directory writer size accounting

2021-07-21T07:56:31+00:00

The squashfs readdir() implementation in the Linux kernel returns non-existing "." and ".." entries for offsets 0 and 1, and after that reads from disk. For convenience, it was decided to store an off-by-3 value on disk instead of doing complex primary school math to adjust for this. This didn't show up until now, because the kernel implementation trusts the value from the directory header more than the actual size in the inode and happily reads 3 more than the inode would allow it to. This only showed up with 7-zip which subtracts 3 from the size and expects the result to be exact and bails if the directory headers suggest otherwise. And yes, I did consider making a "Holy Hand Granade of Antioch" reference, but consciously decided not to. Signed-off-by: David Oberhollenzer

Fix: libsquashfs: allow static linking on Windows

2021-04-09T09:55:04+00:00

If SQFS_STATIC is defined, dummy out the SQFS_API definition, so we don't try to pull stuff from a (in this case) non-existant DLL or try to export functions. Signed-off-by: David Oberhollenzer

Fix: libsquashfs: add sqfs_free() function

2021-04-08T10:04:33+00:00

On systems like Windows, the dynamic library and applications can easily end up being linked against different runtime libraries, so applications cannot be expected to be able to free() any malloc'd pointer that the library returns. This commit adds an sqfs_free function so the application can pass pointers back to the library to call the correct free() implementation. Signed-off-by: David Oberhollenzer

Cleanup the block processor file structure

2021-03-22T14:26:47+00:00

A cleaner separation between common code, frontend code and backend code is made. The "is this byte blob zero" function is moved out to libutil (with test case and everything) with a more optimized implementation. Signed-off-by: David Oberhollenzer

Add a thread pool implementation to libutil

2021-03-21T16:29:18+00:00

The thread pool enforces ordering of items during dequeue similar to the already existing implementation in libsqfs. The idea is to eventually pull this functionality out of the block processor and turn it into a cleaner, separately tested module. The thread pool is implemented as an abstract interface, so we can have multiple implementations around, including the serial fallback implementation which we can then *always* test, irregardless of the compile config and run through static analysis as well.
