* TFTPFS: Implement block and window size optionsFrank Kühndel2022-06-213-658/+1800
| | | | | | | | | | | | | | | | | | | | | The original file cpukit/libfs/src/ftpfs/tftpDriver.c is split into two: tftpfs.c - This file contains the code from tftpDriver.c related to file system operations such as mount(), open(), read(), and so on. tftpDriver.c - In the original file remains only the code related to networking. This code implements the Trivial File Transfer Protocol (TFTP). Moreover, the code is extended to support * RFC 2347 TFTP Option Extension * RFC 2348 TFTP Blocksize Option * RFC 7440 TFTP Windowsize Option Update #4666.

| | | | | | | | | | Replace the existing /* fall through */ comments and its variants with the new pseudo-keyword macro fallthrough[1]. Also, remove unnecessary fall-through markings when it is the case.

* jffs2: fix jffs2 mounting failureZhe Li2022-06-201-1/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Thanks for the advice mentioned in the email. This is my v3 patch for this problem. Mounting jffs2 on nand flash will get message "failed: I/O error" with the steps listed below. 1.umount jffs2 2.erase nand flash 3.mount jffs2 on it (this mounting operation will be successful) 4.do chown or chmod to the mount point directory 5.umount jffs2 6.mount jffs2 on nand flash After step 6, we will get message "mount ... failed: I/O error". Typical image of this problem is like: Empty space found from 0x00000000 to 0x008a0000 Inode node at xx, totlen 0x00000044, #ino 1, version 1, isize 0... The reason for this mounting failure is that at the end of function jffs2_scan_medium(), jffs2 will check the used_size and some info of nr_blocks.If conditions are met, it will return -EIO. The detail is that, in the steps listed above, step 4 will write jffs2_raw_inode into flash without jffs2_raw_dirent, which will cause that there are some jffs2_raw_inode but no jffs2_raw_dirent on flash. This will meet the condition at the end of function jffs2_scan_medium() and return -EIO if we umount jffs2 and mount it again. We notice that jffs2 add the value of c->unchecked_size if we find an inode node while mounting. And jffs2 will never add the value of c->unchecked_size in other situations. So this patch add one more condition about c->unchecked_size of the judgement to fix this problem. Signed-off-by: Zhe Li <lizhe67@huawei.com> Signed-off-by: Richard Weinberger <richard@nod.at>
* treewide: Remove uninitialized_var() usageKees Cook2022-06-201-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Using uninitialized_var() is dangerous as it papers over real bugs[1] (or can in the future), and suppresses unrelated compiler warnings (e.g. "unused variable"). If the compiler thinks it is uninitialized, either simply initialize the variable or make compiler changes. In preparation for removing[2] the[3] macro[4], remove all remaining needless uses with the following script: git grep '\buninitialized_var\b' | cut -d: -f1 | sort -u | \ xargs perl -pi -e \ 's/\buninitialized_var\(([^\)]+)\)/\1/g; s:\s*/\* (GCC be quiet|to make compiler happy) \*/$::g;' drivers/video/fbdev/riva/riva_hw.c was manually tweaked to avoid pathological white-space. No outstanding warnings were found building allmodconfig with GCC 9.3.0 for x86_64, i386, arm64, arm, powerpc, powerpc64le, s390x, mips, sparc64, alpha, and m68k.

* jffs2: Replace zero-length array with flexible-arrayGustavo A. R. Silva2022-06-202-3/+3
| | | | | | | | | | | | There is a regular need in the kernel to provide a way to declare having a dynamically sized set of trailing elements in a structure. Kernel code should always use “flexible array members”[1] for these cases. The older style of one-element or zero-length arrays should no longer be used[2].

* 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.
