* Revert "jffs2: Fix possible null-pointer dereferences in ↵Joel Stanley2022-06-201-1/+1
| | | | | | | | | | | | | | | | | jffs2_add_frag_to_fragtree()" This reverts commit f2538f999345405f7d2e1194c0c8efa4e11f7b3a. The patch stopped JFFS2 from being able to mount an existing filesystem with the following errors: jffs2: error: (77) jffs2_build_inode_fragtree: Add node to tree failed -22 jffs2: error: (77) jffs2_do_read_inode_internal: Failed to build final fragtree for inode #5377: error -22 Fixes: f2538f999345 ("jffs2: Fix possible null-pointer dereferences...")

* jffs2: Fix memory leak in jffs2_scan_eraseblock() error pathWenwen Wang2022-06-201-1/+4
| | | | | | | | | | In jffs2_scan_eraseblock(), 'sumptr' is allocated through kmalloc() if 'sumlen' is larger than 'buf_size'. However, it is not deallocated in the following execution if jffs2_fill_scan_buf() fails, leading to a memory leak bug. To fix this issue, free 'sumptr' before returning the error.

* jffs2: Fix possible null-pointer dereferences in jffs2_add_frag_to_fragtree()Jia-Ju Bai2022-06-201-1/+1
| | | | | | | | | | | | | | | | | | | | In jffs2_add_frag_to_fragtree(), there is an if statement on line 223 to check whether "this" is NULL: if (this) When "this" is NULL, it is used at several places, such as on line 249: if (this->node) and on line 260: if (newfrag->ofs > this->ofs) Thus possible null-pointer dereferences may occur. To fix these bugs, -EINVAL is returned when "this" is NULL. These bugs are found by a static analysis tool STCheck written by us.

* jffs2: Remove C++ style comments from uapi headerMasahiro Yamada2022-06-201-5/+0
| | | | | | | | | | | | | | | | | | | Linux kernel tolerates C++ style comments these days. Actually, the SPDX License tags for .c files start with //. On the other hand, uapi headers are written in more strict C, where the C++ comment style is forbidden. I simply dropped these lines instead of fixing the comment style. This code has been always commented out since it was added around Linux 2.4.9 (i.e. commented out for more than 17 years). 'Maybe later...' will never happen.

* imfs: Fix index underrun when extending empty fileChristian Mauderer2022-04-071-1/+2
| | | | | | | | | | | | | | | | | | | | | | | Currently the following sequence causes a endless loop when extending an IMFS file: - Create a file with zero length and close it. - Make sure nearly no allocatable memory is left. - Open the file and write enough data into it that more than the remaining memory will be used. In that case when extending the IMFS file, the file currently need zero blocks. If allocating enough new blocks fails, the already allocated new blocks will be freed again. The comparison of block>=old_blocks that has been used prior to this patch compared two unsigned numbers. If old_blocks was zero, the comparison of these two numbers always evaluated to true. This patch frees the last block in a separate step to avoid this problem. Fixes #4639

* dosfs: Fix memory leak on failed mounts.Christian Mauderer2020-08-041-0/+5
| | | | | | | | | | | | | | | | | | | | Currently if mount fails, a converter isn't destroyed. We have to take care of two cases: 1. The user doesn't provide a converter. In this case mounting a dosfs creates a default converter. This patch makes sure that the converter is destroyed again if mount failes for this case. 2. The user provides a converter. In this case it's not sure that the dosfs specific routines are reached because mount can fail before that. Therefore the user has to destroy the converter himself again. This patch adds a documentation for that and implements it in the media server. Closes #4042.
