* | fincore: Handle large files on 32 bit without LFSTobias Stoeckmann2018-02-261-3/+2Star
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | If util-linux is installed on a system without large file support, an out of memory issue can occur while processing a file which is 2 GB in size: $ ./configure --disable-largefile && make $ dd if=/dev/zero of=2gb-file seek=2147483646 count=1 bs=1 $ fincore 2gb-file (endless loop) fincore: failed to do mmap: 2gb-file: Cannot allocate memory Even though iterating with "len" seems counter-intuitive, it fixes this issue. The variable len is only in the last iteration not a multiplication of pagesize -- which is the requirement for mmap. Signed-off-by: Tobias Stoeckmann <tobias@stoeckmann.org>
* | fincore: Handle large files correctly on 32 bitTobias Stoeckmann2018-02-261-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | If a file is larger than 4 GB on a 32 bit system with large file support (default), it can happen that not all pages are properly processed. This happens due to an int truncation (off_t vs size_t). You can reproduce this on 32 bit with these commands: $ dd if=/dev/zero of=4gb-file seek=4294967295 count=1 bs=1 $ fincore 4gb-file fincore: failed to do mmap: 4gb-file: Invalid argument If a file is larger than 4 GB, the first few pages of a file won't be properly processed. "len" will be smaller than window_size, but the for-loop iterates "window_size" bytes, skipping some pages. Signed-off-by: Tobias Stoeckmann <tobias@stoeckmann.org>

* | cal: honor num_months when only a year argumentJ William Piggott2018-01-241-3/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | I don't know if this was an oversight or an overzealous interpretation of POSIX. Just in case, I'll address the POSIX possibility. POSIX description for cal(1) says: If only the year operand is given, cal shall produce a calendar for all twelve months in the given calendar year. It also says that cal(1) has no options, so in that context if an option is given then it should be expected to override POSIX behavior. Before patched all of these command displayed a full year: cal -1 2020 cal -3 2020 cal -n6 2020 Patched the number of months options are honored. This patch also fixes the -1 option which was a no-op. Signed-off-by: J William Piggott <elseifthen@gmx.com>
