MMAP support for 2.3.XX is missing and MMAP will + lead to Oops. + +- In some 2.1.XX kernels umsdos support is broken. Get at least 2.1.94 + if you want to use umsdos-style long filenames in CVFs. For 2.0.xx + and 2.2.x kernels everything is okay. + +- Advanced memory allocation (XMALLOC) may crash a 2.1.xx/2.2.xx system. + I once got a report of a serious crash with old dmsdosfs. The code + for XMALLOC has never been changed, but the kernel keeps changing... + It is known to work without problems under 2.0.xx. + +- Writable mmap support must be turned *on* for newer 2.1.xx and all 2.2.xx + kernels. The code fails to compile if it is switched off, so you'll see it + quite early :) + +- Mounting with the cvf_format=xxx mount option may succeed even if the + specified format xxx is not present. The CVF-FAT interface does auto- + detection if an invalid format is specified. This was meant as a feature + but seems to cause confusion. In rare cases it may lead to a CVF accessed + by the plain FAT driver (which does not complain on mount but it will + scream loudly when, for example, a 'ls' is done on the mount point). + This bug is fixed by updating the file cvf.c as described in INSTALL.TXT. + + +Kernel bugs related to using dmsdos +----------------------------------- + +- vfat brelse bug + Priority: Serious. + Affected kernels: 2.2.0, 2.2.1, 2.2.2, probably late 2.1.xx. + Fixed since: --not yet fixed, hopefully fixed in 2.2.3 or 2.2.4-- + Symptom: Kernel panics with "VFS: LRU list corrupted" and hangs. + Fix: See file patches/DIFFS.TXT for a patch. + +- fat truncate bug + Priority: Minor. + Affected kernels: all 2.0.xx, all 2.1.xx, 2.2.0, 2.2.1, 2.2.2. + Fixed since: --not yet fixed, hopefully fixed in 2.2.3 or 2.2.4-- + Symptom: Kernel can write to read-only mounted CVF and corrupt the FAT. + Happens very rarely and requires a slightly damaged filesystem + to provoke this bug. + Fix: See file patches/DIFFS.TXT for a patch. + +- msdos rmdir bug + Priority: Minor. + Affected kernels: 2.0.34, 2.0.35, FAT32-patched 2.0.33 or earlier, + some 2.1.xx (unknown which ones) + Fixed since: 2.0.36, unknown for 2.1.xx + Symptom: Removing non-empty directories succeeds but leaves lost cluster + chains behind. + Fix: See file patches/DIFFS.TXT for a patch. + +- fat add cluster / fat extend dir for 2.3.xx + Priority: Serious. + Affected kernels: 2.2.?-2.2.13+, 2.3.?-2.3.30+ + Fixed since: --not yet fixed, hopefully fixed in 2.2.15 and 2.3.31-- + Symptom: File or directory (only dir for 2.3.x) cannot be enlargered. + Fix: See file patches/DIFFS.TXT for a patch. + +- fat read super + Priority: Serious. + Affected kernels: 2.3.?-2.3.30+ + Fixed since: --not yet fixed, hopefully fixed in 2.3.31-- + Symptom: Oops during CVF mount phase. + Fix: See file patches/DIFFS.TXT for a patch. + |
