Vincent Perrier perrier.vincent0210 at gmail.comFix memory leak in librtlsdr. The problem came up when using rtlsdr_open() twice with the same index. The variable dev->devh is never cleaned if libusb_claim_interface() fails. This causes a leak if the device is already claimed by another handle. rtlsdr_close() did not free that space since the returned handle is invalid if libusb_claim_interface fails Here is the patch file in text format. (it is also joined to this email). ~~~~ diff --git a/src/librtlsdr.c b/src/librtlsdr.c index a71609b..89ec903 100644 --- a/src/librtlsdr.c +++ b/src/librtlsdr.c @@ -1520,10 +1520,6 @@ int rtlsdr_open(rtlsdr_dev_t **out_dev, uint32_t index) r = libusb_claim_interface(dev->devh, 0); if (r < 0) { fprintf(stderr, "usb_claim_interface error %d\n", r); - if (dev) - { - libusb_close(dev->devh); - } goto err; } ~~~~ -Vincent Perrier -------------- next part -------------- An HTML attachment was scrubbed...
