4Subject: [PATCH] btt: make device/devno use PATH_MAX to avoid overflow
5
6Herbo Zhang reports:
7
8I found a bug in blktrace/btt/devmap.c. The code is just as follows:
9
10https://git.kernel.org/pub/scm/linux/kernel/git/axboe/blktrace.git/tree/btt/devmap.c?id=8349ad2f2d19422a6241f94ea84d696b21de4757
11
12 struct devmap {
13
14struct list_head head;
15char device[32], devno[32]; // #1
16};
17
18LIST_HEAD(all_devmaps);
19
20static int dev_map_add(char *line)
21{
22struct devmap *dmp;
23
24if (strstr(line, "Device") != NULL)
25return 1;
26
27dmp = malloc(sizeof(struct devmap));
28if (sscanf(line, "%s %s", dmp->device, dmp->devno) != 2) { //#2
29free(dmp);
30return 1;
31}
32
33list_add_tail(&dmp->head, &all_devmaps);
34return 0;
35}
36
37int dev_map_read(char *fname)
38{
39char line[256]; // #3
40FILE *fp = my_fopen(fname, "r");
41
42if (!fp) {
43perror(fname);
44return 1;
45}
46
47while (fscanf(fp, "%255[a-zA-Z0-9 :.,/_-]\n", line) == 1) {
48if (dev_map_add(line))
49break;
50}
51
52fclose(fp);
53return 0;
54}
55
56 The line length is 256, but the dmp->device, dmp->devno max length
57is only 32. We can put strings longer than 32 into dmp->device and
58dmp->devno , and then they will be overflowed.
59
60 we can trigger this bug just as follows:
61
62 $ python -c "print 'A'*256" > ./test
63 $ btt -M ./test
64
65 *** Error in btt': free(): invalid next size (fast): 0x000055ad7349b250 ***

4Subject: [oe-core][PATCH 1/1] make btt scripts python3-ready
5
6Many distributions are moving to python3 by default. Here's
7an attempt to make the python scripts in blktrace python3-ready.
8
9Most of this was done with automated tools. I hand fixed some
10space-vs tab issues, and cast an array index to integer. It
11passes rudimentary testing when run under python2.7 as well
12as python3.
13
14This doesn't do anything with the shebangs, it leaves them both
15invoking whatever "env python" coughs up on the system.

19
20Unchanged except to modify shebangs to use python3 since
21oe-core does not support python2 anymore.
