Shang XiaoJing says: ==================== nfc: Fix potential memory leak of skb There are 6 kinds of send functions can be called by nci_send_frame(): virtual_nci_send(), fdp_nci_send(), nxp_nci_send(), s3fwrn5_nci_send(), nfcmrvl_nci_send(), st_nci_send(); 1. virtual_nci_send() will memleak the skb, and has been fixed before. 2. fdp_nci_send() won't free the skb no matter whether write() succeed. 3-4. nxp_nci_send() and s3fwrn5_nci_send() will only free the skb when write() failed, however write() will not free the skb by itself for when succeeds. 5. nfcmrvl_nci_send() will call nfcmrvl_XXX_nci_send(), where some of them will free the skb, but nfcmrvl_i2c_nci_send() only free the skb when i2c_master_send() return >=0, and memleak will happen when i2c_master_send() failed in nfcmrvl_i2c_nci_send(). 6. st_nci_send() will queue the skb into other list and finally be freed. Fix the potential memory leak of skb. ==================== Signed-off-by: David S. Miller <davem@davemloft.net> |

Linux kernel ============ There are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. Please read Documentation/admin-guide/README.rst first. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. The formatted documentation can also be read online at: https://www.kernel.org/doc/html/latest/ There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. Please read the Documentation/process/changes.rst file, as it contains the requirements for building and running the kernel, and information about the problems which may result by upgrading your kernel.
