For example, in the get_tree_bdev_flags function,when encountering the situation where "Can't mount, would change RO state," In such a case, isofs_fill_super will not have the opportunity to be called,which means that opt->iocharset will not have the chance to be freed,ultimately leading to a memory leak. Let's move the memory freeing of opt->iocharset into isofs_free_fc function.

* isofs: handle CDs with bad root inode but good Joliet root directoryAlex Henrie2024-02-081-2/+16
| | | | | | | | | | | | | | | | | I have a CD copy of the original Tom Clancy's Ghost Recon game from 2001. The disc mounts without error on Windows, but on Linux mounting fails with the message "isofs_fill_super: get root inode failed". The error originates in isofs_read_inode, which returns -EIO because de_len is 0. The superblock on this disc appears to be intentionally corrupt as a form of copy protection. When the root inode is unusable, instead of giving up immediately, try to continue with the Joliet file table. This fixes the Ghost Recon CD and probably other copy-protected CDs too.

| * fs/isofs: replace kmap() with kmap_local_page()Fabio M. De Francesco2022-09-111-10/+10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The use of kmap() is being deprecated in favor of kmap_local_page(). There are two main problems with kmap(): (1) It comes with an overhead as mapping space is restricted and protected by a global lock for synchronization and (2) it also requires global TLB invalidation when the kmap's pool wraps and it might block when the mapping space is fully utilized until a slot becomes available. With kmap_local_page() the mappings are per thread, CPU local, can take page faults, and can be called from any context (including interrupts). Tasks can be preempted and, when scheduled to run again, the kernel virtual addresses are restored and still valid. It is faster than kmap() in kernels with HIGHMEM enabled. Since kmap_local_page() can be safely used in compress.c, it should be called everywhere instead of kmap(). Therefore, replace kmap() with kmap_local_page() in compress.c. Where it is needed, use memzero_page() instead of open coding kmap_local_page() plus memset() to fill the pages with zeros. Delete the redundant flush_dcache_page() in the two call sites of memzero_page(). Tested with mkisofs on a QEMU/KVM x86_32 VM, 6GB RAM, booting a kernel with HIGHMEM64GB enabled.
