udf: udftime: prevent overflow in udf_disk_stamp_to_time()

2024-04-10T11:10:12+00:00

An overflow can occur in a situation where src.centiseconds takes the value of 255. This situation is unlikely, but there is no validation check anywere in the code. Found by Linux Verification Center (linuxtesting.org) with Svace.

udf: convert inode stamps to timespec64

2018-06-27T11:58:00+00:00

The VFS structures are finally converted to always use 64-bit timestamps, and this file system can represent a long range of on-disk timestamps already, so now let's fit in the missing bits for udf. Signed-off-by: Arnd Bergmann Signed-off-by: Jan Kara

udf: Simplify calls to udf_disk_stamp_to_time

2018-05-25T22:31:14+00:00

Subsequent patches in the series convert inode timestamps to use struct timespec64 instead of struct timespec as part of solving the y2038 problem. commit fd3cfad374d4 ("udf: Convert udf_disk_stamp_to_time() to use mktime64()") eliminated the NULL return condition from udf_disk_stamp_to_time(). udf_time_to_disk_time() is always called with a valid dest pointer and the return value is ignored. Further, caller can as well check the dest pointer being passed in rather than return argument. Make both the functions return void. This will make the inode timestamp conversion simpler.

udf: Sanitize nanoseconds for time stamps

2017-12-19T07:11:01+00:00

Reportedly some UDF filesystems are recorded with bogus subsecond values resulting in nanoseconds being over 10^9. Sanitize nanoseconds in time stamps when loading them from disk. Reported-by: Ian Turner Signed-off-by: Jan Kara

udf: Convert udf_disk_stamp_to_time() to use mktime64()

2017-06-14T09:21:02+00:00

Convert udf_disk_stamp_to_time() to use mktime64() to simplify the code. As a bonus we get working timestamp conversion for dates before epoch and after 2038 (both of which are allowed by UDF standard). Signed-off-by: Jan Kara

udf: Use time64_to_tm for timestamp conversion

2017-06-14T09:21:02+00:00

UDF on-disk time stamp is stored in a form very similar to struct tm. Use time64_to_tm() for conversion of seconds since epoch to year, month, ... format and then just copy this as necessary to UDF on-disk structure to simplify the code. Signed-off-by: Jan Kara

udf: Convert printks to pr_

2011-10-31T22:43:52+00:00

Use the current logging styles. Convert a few printks that should have been udf_warn and udf_err. Coalesce formats. Add #define pr_fmt. Move an #include "udfdecls.h" above other includes in udftime.c so pr_fmt works correctly. Strip prefixes from conversions as appropriate.
