File s390-tools-sles11sp2-dasdview-fix-busid-output.patch of Package s390-tools
Description: dasdview: fix printing of random characters after busid Symptom: When option -i or -x is used to print information about a device, then the busid in this output is sometimes followed by random characters. Problem: The libu2s library function find_busid_in_proc copies a string without the terminating zero. If this string is copied into a buffer that contains random data, this data is later printed as part of the busid. Solution: Specifying a correct buffer length for the copy command fixes this problem. Problem-ID: 75781 --- libu2s/u2s.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) --- a/libu2s/u2s.c +++ b/libu2s/u2s.c @@ -239,7 +239,7 @@ static int find_busid_in_proc(int maja, while (fscanf(filp, "%[^(] %*s at ( %d : %d %*[^\n]\n", bus, &majb, &minb) != EOF) { if ((maja == majb) && (mina == minb)) { - strncpy(busid, bus, BUSIDSIZE); + strncpy(busid, bus, BUSIDSIZE + 1); rc = 0; break; }
